Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis Of Presentation And Organization	BASIS OF PRESENTATION AND ORGANIZATION The accompanying unaudited condensed consolidated financial statements have been prepared by the management of Columbia Sportswear Company (together with its wholly owned subsidiaries and entities in which it maintains a controlling financial interest, the "Company") and in the opinion of management include all normal recurring material adjustments necessary to present fairly the Company's financial position as of September 30, 2018 and 2017 , the results of operations for the three and nine months ended September 30, 2018 and 2017 , and cash flows for the nine months ended September 30, 2018 and 2017 . The December 31, 2017 financial information was derived from the Company's audited financial statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 . A significant part of the Company's business is of a seasonal nature; therefore, results of operations for the three and nine months ended September 30, 2018 are not necessarily indicative of results to be expected for other quarterly periods or for the full year. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The Company, however, believes that the disclosures contained in this report comply with the requirements of Section 13(a) of the Securities Exchange Act of 1934 for a Quarterly Report on Form 10-Q and are adequate to make the information presented not misleading. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 . Principles of Consolidation The condensed consolidated financial statements include the accounts of Columbia Sportswear Company, its wholly owned subsidiaries and entities in which it maintains a controlling financial interest. All significant intercompany balances and transactions have been eliminated in consolidation. Estimates and Assumptions The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from these estimates and assumptions. Some of these more significant estimates relate to revenue recognition, including sales returns and miscellaneous claims from customers, allowance for doubtful accounts, excess, slow-moving and closeout inventories, product warranty, long-lived and intangible assets, goodwill, income taxes, and stock-based compensation.

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Except as disclosed below and in Note 3, pertaining to our adoption of new accounting pronouncements, there have been no significant changes to the Company's significant accounting policies as described in the Company's Annual Report on Form 10-K for the year ended December 31, 2017 . Recently Adopted Accounting Pronouncements: On January 1, 2018, the Company adopted Accounting Standards Update ("ASU") No. 2014-09, R evenue from Contracts with Customers, which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers that superseded the previous revenue recognition guidance (Topic 605). The updated guidance, and subsequent clarifications, collectively referred to as ASC 606, require an entity to recognize revenue when it transfers control of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In addition, the guidance requires disclosure of the nature, amount, timing and uncertainty of revenue and cash flows arising from contracts with customers. The Company adopted this standard, utilizing the modified retrospective approach, with the cumulative effect of initially applying the new standard recognized in retained earnings. Accordingly, comparative prior period information has not been restated and continues to be reported under the accounting standards in effect for those periods. In addition, the adoption of ASC 606 had the following effects: (1) fees paid to or retained by third parties in conjunction with certain concession-based retail arrangements in our Latin America and Asia Pacific ("LAAP") region, historically comprising approximately 2% of net sales, are now recognized as a component of selling, general and administrative ("SG&A") expenses; (2) wholesale sales returns reserves, estimated chargebacks and markdowns, and other provisions for customer refunds are now presented as accrued liabilities rather than netted within accounts receivable; and (3) the estimated cost of inventory associated with sales returns reserves are now presented within other current assets rather than inventories. The Company expects the timing of revenue recognition for its significant revenue streams to remain substantially unchanged, with no material effect on net sales. See the table below for the effect of the adoption of the standard on our Condensed Consolidated Balance Sheets as of January 1, 2018. On January 1, 2018, the Company adopted ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfer of Assets Other than Inventory , which requires the recognition of the income tax effects of an intra-entity transfer of an asset, other than inventory, when the transfer occurs, eliminating an exception under previous GAAP in which the tax effects of intra-entity asset transfers were deferred until the transferred asset is sold to a third party or otherwise recovered through use. Income tax effects of intra-entity transfers of inventory will continue to be deferred until the inventory has been sold to a third party. The Company adopted this standard effective January 1, 2018 by applying the required modified retrospective approach with a cumulative-effect adjustment to retained earnings of certain previously deferred tax benefits. The Company anticipates the adoption of this standard will result in increased volatility in its future effective income tax rate. See the table below for the effect of the adoption of the standard on our Condensed Consolidated Balance Sheets as of January 1, 2018. On January 1, 2018, the Company early-adopted ASU No. 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities , which simplifies the application of hedge accounting guidance to better portray the economic results of risk management activities in the financial statements. The guidance aligns the recognition and presentation of the effects of hedging instruments and hedged items in the financial statements and includes certain targeted improvements to ease the application of the assessment of hedge effectiveness. The Company utilized the required modified retrospective transition method with the cumulative effect of initially applying the new standard recognized in retained earnings. See the table below for the effect of the adoption of the standard on our Condensed Consolidated Balance Sheets as of January 1, 2018. On January 1, 2018, the Company adopted ASU No. 2016-01, Financial Instruments - Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , which requires equity investments that are not accounted for under the equity method of accounting to be measured at fair value with changes recognized in net income and also updates certain presentation and disclosure requirements. The adoption of this standard did not have a material effect on the Company's financial position, results of operations or cash flows. The following table presents the effect of the adoption of ASC 606, ASU 2016-16 and ASU 2017-12 on our Condensed Consolidated Balance Sheets as of January 1, 2018 (in thousands): January 1, 2018 December 31, 2017 Adjustments due to ASC 606 Adjustments due to ASU 2016-16 Adjustments due to ASU 2017-12 January 1, 2018 Accounts receivable, net $ 364,862 $ 64,519 $ — $ — $ 429,381 Inventories 457,927 (24,037 ) — — 433,890 Prepaid expenses and other current assets 58,559 24,037 (11,814 ) — 70,782 Total current assets 1,649,497 64,519 (11,814 ) — 1,702,202 Deferred income taxes 56,804 (519 ) 23,484 — 79,769 Total assets 2,212,902 64,000 11,670 — 2,288,572 Accrued liabilities 182,228 61,340 — — 243,568 Income taxes payable 19,107 230 — — 19,337 Total current liabilities 453,636 61,570 — — 515,206 Total liabilities 560,643 61,570 — — 622,213 Retained earnings 1,585,009 2,430 11,670 515 1,599,624 Accumulated other comprehensive loss (8,887 ) — — (515 ) (9,402 ) Total liabilities and equity $ 2,212,902 $ 64,000 $ 11,670 $ — $ 2,288,572 In accordance with the requirements of ASC 606, the effects of adoption of this standard on our Condensed Consolidated Balance Sheets and Condensed Consolidated Statements of Operations were as follows (in thousands): September 30, 2018 As Reported Effect of Standard Balances Without Adoption of ASC 606 Accounts receivable, net $ 552,442 $ 59,921 $ 492,521 Inventories 617,194 (16,012 ) 633,206 Prepaid expenses and other current assets 77,763 16,012 61,751 Total current assets 1,712,857 59,921 1,652,936 Total assets 2,299,339 59,921 2,239,418 Accrued liabilities 255,682 59,921 195,761 Total current liabilities 509,584 59,921 449,663 Total liabilities 617,743 59,921 557,822 Total liabilities and equity $ 2,299,339 $ 59,921 $ 2,239,418 Three Months Ended Nine Months Ended As Reported Effect of Standard Balances Without Adoption of ASC 606 As Reported Effect of Standard Balances Without Adoption of ASC 606 Net sales $ 795,801 $ 6,913 $ 788,888 $ 1,884,728 $ 22,657 $ 1,862,071 Gross profit 383,703 6,913 376,790 911,762 22,657 889,105 Selling, general and administrative expenses $ 259,267 $ 6,913 $ 252,354 $ 724,827 $ 22,657 $ 702,170 Recent Accounting Pronouncements Not Yet Adopted In February 2016, the Financial Accounting Standards Board ("FASB") issued ASU No. 2016-02, Leases (Topic 842), to increase transparency and comparability among organizations by recognizing lease assets and lease liabilities on the balance sheet for most leases previously classified as operating leases. Subsequently, the FASB has issued amendments to clarify the codification or to correct unintended application of the new guidance. The new standard is required to be applied using a modified retrospective approach, with two adoption methods permissible: (1) apply the leases standard to each lease that existed at the beginning of the earliest comparative period presented in the financial statements or (2) apply the guidance to each lease that had commenced as of the beginning of the reporting period in which the entity first applies the new lease standard. The Company will adopt the new standard on January 1, 2019 and anticipates applying the second modified retrospective method noted above. The Company is continuing to evaluate the impact of the guidance, including reviewing the standard's provisions, gathering and analyzing data to support further evaluation of real estate and non-real estate leases, identifying arrangements that may contain embedded leases and assessing practical expedients. The Company is also evaluating the impact of the new accounting standard on the Company's financial statement disclosures, systems, processes and controls. Based on these efforts, the Company expects the adoption will result in a material increase in the assets and liabilities on its Consolidated Balance Sheets and is not expected to have a material effect on the results of operations or cash flows. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments . The pronouncement changes the impairment model for most financial assets and will require the use of an " expected loss " model for instruments measured at amortized cost. Under this model, entities will be required to estimate the lifetime expected credit loss on such instruments and record an allowance to offset the amortized cost basis of the financial asset, resulting in a net presentation of the amount expected to be collected on the financial asset. Subsequently, the FASB issued an amendment to clarify the implementation dates and items that fall within the scope of this pronouncement. This standard is effective beginning in the first quarter of 2020. The adoption of ASU 2016-13 is not expected to have a material effect on the Company's financial position, results of operations or cash flows. In January 2017, the FASB issued ASU No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment , which simplifies the accounting for goodwill impairments by eliminating step two from the goodwill impairment test. Under this guidance, if the carrying amount of a reporting unit exceeds its estimated fair value, an impairment charge shall be recognized in an amount equal to that excess, limited to the total amount of goodwill allocated to that reporting unit. This standard is effective beginning in the first quarter of 2019, with early adoption permitted. The Company is evaluating the impact and expects the adoption of ASU 2017-04 to affect the amount and timing of future goodwill impairment charges, if any. In June 2018, the FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting , which simplifies the accounting for share-based payments granted to nonemployees for goods and services. Under the ASU, most of the guidance on such payments to nonemployees would be aligned with the requirements for share-based payments granted to employees. As a result, most of the guidance in ASC 718 associated with employee share-based payments, including most requirements related to classification and measurement, applies to nonemployee share-based payment arrangements. This standard is effective beginning in the first quarter of 2019, with early adoption permitted. The Company is currently evaluating the impact this accounting standard will have on the Company's financial position, results of operations or cash flows. In August 2018, the FASB issued ASU No. 2018-15, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40), which clarifies certain aspects of accounting for implementation costs incurred in a cloud computing arrangement ("CCA") that is a service contract. Under the ASU, an entity would expense costs incurred in the preliminary-project and post-implementation-operation stages. The entity would also capitalize certain costs incurred during the application-development stage, as well as certain costs related to enhancements. The ASU does not change the accounting for the service component of a CCA. This standard is effective beginning in the first quarter of 2020, with early adoption permitted. The Company is currently evaluating the impact this accounting standard will have on the Company's financial position, results of operations or cash flows.

Within our wholesale channel, control generally transfers to the customer upon shipment to, or upon receipt by, the customer depending on the terms of sale with the customer. Within our direct-to-consumer ("DTC") channel, control generally transfers to the customer at the time of sale within our retail stores and concession-based arrangements and upon shipment to the customer with respect to e-commerce transactions. The amount of consideration we receive and revenue we recognize across both wholesale and DTC channels varies with changes in sales returns and other accommodations and incentives we offer to our customers. When we give our customers the right to return products or provide other accommodations such as chargebacks and markdowns, we estimate the expected returns and claims based on historical rates as well as events and circumstances that indicate changes to historical rates of product returns and claims. We adjust our estimates of revenue at the earlier of when the most likely amount of consideration we expect to receive changes or when the amount of consideration becomes fixed. Licensing income, which is presented separately as Net licensing income on the Condensed Consolidated Statements of Operations and represents less than 1% of total revenue, is recognized over time based on the greater of contractual minimum royalty guarantees and actual, or estimated, sales of licensed products by our licensees. We expense sales commissions when incurred, which is generally at the time of sale, because the amortization period would have been one year or less. These costs are recorded within SG&A expenses . We treat shipping and handling activities as fulfillment costs, and as such recognize the costs for these activities at the time related revenue is recognized. The majority of these costs are recorded as SG&A expenses , and the direct costs associated with shipping goods to customers and consumers are recorded as Costs of goods sold . Shipping and handling fees billed to customers are recorded as revenue. Revenue recognized from contracts with customers is recorded net of sales taxes, value added taxes, or similar taxes that are collected on behalf of local taxing authorities. Performance Obligations For the three and nine months ended September 30, 2018 , revenue recognized from performance obligations related to prior periods was not material. Revenue expected to be recognized in any future period related to remaining performance obligations is not material. Contract Balances As of September 30, 2018 , contract liabilities recorded on the Condensed Consolidated Balance Sheets, which consisted of obligations associated with our gift card and customer loyalty programs, were not material.

Earnings Per Share [Abstract]
Earnings Per Share	EARNINGS PER SHARE Earnings per share ("EPS") is presented on both a basic and diluted basis. Basic EPS is based on the weighted average number of common shares outstanding. Diluted EPS reflects the potential dilution that could occur if outstanding securities or other contracts to issue common stock were exercised or converted into common stock. A reconciliation of common shares used in the denominator for computing basic and diluted EPS is as follows (in thousands, except per share amounts): Three Months Ended September 30, Nine Months Ended September 30, 2018 2017 2018 2017 Weighted average shares of common stock outstanding, used in computing basic earnings per share 69,589 69,815 69,895 69,698 Effect of dilutive stock options and restricted stock units 768 574 790 692 Weighted average shares of common stock outstanding, used in computing diluted earnings per share 70,357 70,389 70,685 70,390 Earnings per share of common stock attributable to Columbia Sportswear Company: Basic $ 1.44 $ 1.26 $ 2.22 $ 1.61 Diluted $ 1.42 $ 1.25 $ 2.19 $ 1.59 Stock options and service-based restricted stock units representing 216,386 and 931,524 shares of common stock for the three months ended September 30, 2018 and 2017 , respectively, were outstanding but were excluded from the computation of diluted EPS because their effect would be anti-dilutive as a result of applying the treasury stock method. Stock options and service-based restricted stock units representing 325,410 and 887,508 shares of common stock for the nine months ended September 30, 2018 and 2017 , respectively, were outstanding but were excluded from the computation of diluted EPS because their effect would be anti-dilutive as a result of applying the treasury stock method. In addition, performance-based restricted stock units representing 23,971 and 36,589 shares of common stock for the three months ended September 30, 2018 and 2017 , respectively, and 23,971 and 43,292 shares of common stock for the nine months ended September 30, 2018 and 2017 , respectively, were outstanding but were excluded from the computation of diluted EPS because these shares were subject to performance conditions that had not been met. Common Stock Repurchase Plan Since the inception of the Company's stock repurchase plan in 2004 through September 30, 2018 , the Company's Board of Directors has authorized the repurchase of $900,000,000 of the Company's common stock. Shares of the Company's common stock may be purchased in the open market or through privately negotiated transactions, subject to market conditions. The repurchase program does not obligate the Company to acquire any specific number of shares or to acquire shares over any specified period of time.

Derivative Instruments and Hedges, Assets [Abstract]
Financial Instruments And Risk Management	FINANCIAL INSTRUMENTS AND RISK MANAGEMENT In the normal course of business, the Company's financial position, results of operations and cash flows are routinely subject to a variety of risks. These risks include risks associated with financial markets, primarily currency exchange rate risk and, to a lesser extent, interest rate risk and equity market risk. The Company regularly assesses these risks and has established policies and business practices designed to mitigate them. The Company does not engage in speculative trading in any financial market. The Company actively manages the risk of changes in functional currency equivalent cash flows resulting from anticipated non-functional currency denominated purchases and sales. Subsidiaries that use European euros, Canadian dollars, Japanese yen, Chinese renminbi, or Korean won as their functional currency are primarily exposed to changes in functional currency equivalent cash flows from anticipated U.S. dollar inventory purchases. The Company's prAna subsidiary uses U.S. dollars as its functional currency and is exposed to anticipated Canadian dollar denominated sales. The Company manages these risks by using currency forward and option contracts formally designated and effective as cash flow hedges. Hedge effectiveness is generally determined by evaluating the ability of a hedging instrument's cumulative change in fair value to offset the cumulative change in the present value of expected cash flows on the underlying exposures. For forward contracts, forward points are excluded from the determination of hedge effectiveness and are included in current period cost of sales for hedges of anticipated U.S. dollar inventory purchases and in net sales for hedges of anticipated Canadian dollar sales on a straight-line basis over the life of the contract. In each accounting period, any difference between the change in fair value of the forward points and the amount recognized in earnings on a straight-line basis is recognized in Other comprehensive income in the Condensed Consolidated Statements of Comprehensive Income. For option contracts, the change in fair value attributable to changes in time value are excluded from the assessment of hedge effectiveness and included in current period Cost of sales in the Condensed Consolidated Statements of Operations. Hedge ineffectiveness was not material during the three and nine months ended September 30, 2018 and 2017 . The Company also uses currency forward contracts not formally designated as hedges to manage the consolidated currency exchange rate risk associated with the remeasurement of non-functional currency denominated monetary assets and liabilities by subsidiaries that use U.S. dollars, euros, Canadian dollars, yen, won, or renminbi as their functional currency. Non-functional currency denominated monetary assets and liabilities consist primarily of cash and cash equivalents, short-term investments, receivables, payables, deferred income taxes, and intercompany loans. The gains and losses generated on these currency forward contracts not formally designated as hedges are expected to be largely offset in other non-operating expense, net by the gains and losses generated from the remeasurement of the non-functional currency denominated monetary assets and liabilities. The following table presents the gross notional amount of outstanding derivative instruments (in thousands): September 30, December 31, September 30, Derivative instruments designated as cash flow hedges: Currency forward contracts $ 434,738 $ 448,448 $ 390,500 Derivative instruments not designated as cash flow hedges: Currency forward contracts 289,772 231,161 181,045 At September 30, 2018 , approximately $3,247,000 of deferred net gains on both outstanding and matured derivatives accumulated in Other comprehensive income are expected to be reclassified to net income during the next twelve months as a result of underlying hedged transactions also being recorded in net income. Actual amounts ultimately reclassified to Net income in the Condensed Consolidated Statements of Comprehensive Income are dependent on U.S. dollar exchange rates in effect against the euro, renminbi, Canadian dollar, and yen when outstanding derivative contracts mature. At September 30, 2018 , the Company's derivative contracts had a remaining maturity of less than three years. The maximum net exposure to any single counterparty, which is generally limited to the aggregate unrealized gain of all contracts with that counterparty, was less than $5,000,000 at September 30, 2018 . All of the Company's derivative counterparties have investment grade credit ratings. The Company is a party to master netting arrangements that contain features that allow counterparties to net settle amounts arising from multiple separate derivative transactions or net settle in the case of certain triggering events such as a bankruptcy or major default of one of the counterparties to the transaction. The Company has not pledged assets or posted collateral as a requirement for entering into or maintaining derivative positions.

Fair Value Disclosures [Abstract]
Fair Value Measures	FAIR VALUE MEASURES Certain assets and liabilities are reported at fair value on either a recurring or nonrecurring basis. Fair value is defined as an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants, under a three-tier fair value hierarchy that prioritizes the inputs used in measuring fair value as follows: Level 1 — observable inputs such as quoted prices for identical assets or liabilities in active liquid markets; Level 2 — inputs, other than the quoted market prices in active markets, that are observable, either directly or indirectly; or observable market prices in markets with insufficient volume or infrequent transactions; and Level 3 — unobservable inputs for which there is little or no market data available, that require the reporting entity to develop its own assumptions. Assets and liabilities measured at fair value on a recurring basis as of September 30, 2018 are as follows (in thousands): Level 1 Level 2 Level 3 Total Assets: Cash equivalents: Money market funds $ 70,573 $ — $ — $ 70,573 Available-for-sale short-term investments (1) : U.S. Government treasury bills — 267,861 — 267,861 Other short-term investments: Mutual fund shares 1,452 — — 1,452 Other current assets: Derivative financial instruments (Note 12) — 8,127 — 8,127 Other non-current assets: Derivative financial instruments (Note 12) — 7,963 — 7,963 Mutual fund shares 9,950 — — 9,950 Total assets measured at fair value $ 81,975 $ 283,951 $ — $ 365,926 Liabilities: Accrued liabilities: Derivative financial instruments (Note 12) $ — $ 738 $ — $ 738 Total liabilities measured at fair value $ — $ 738 $ — $ 738 (1) Investments have remaining maturities of less than one year.

Related Party Transactions [Abstract]
Related Party Transactions	RELATED PARTY TRANSACTIONS The Company owns a 60% controlling interest in a joint venture formed with Swire, which is a related party. The joint venture arrangement involves Transition Services Agreements ("TSAs") with Swire, under which Swire provides administrative and information technology services to the joint venture. The Company continues to reduce its costs under the TSAs as it internalizes the back-office functions and related personnel, including the transition of the joint venture's systems to the Company's enterprise resource planning ("ERP") platform in the second quarter of 2017. The joint venture incurred service fees, valued under the TSAs at Swire's cost, of approximately $72,000 and $90,000 during the three months ended September 30, 2018 and 2017 , respectively, and approximately $216,000 and $935,000 during the nine months ended September 30, 2018 and 2017 , respectively. These fees are included in SG&A expenses in the Condensed Consolidated Statements of Operations. As of September 30, 2018 and 2017 , and December 31, 2017 , net payables to Swire for service fees, interest expense and miscellaneous expenses totaled approximately $83,000 , $87,000 and $89,000 , respectively, and were included in Accounts payable in the Condensed Consolidated Balance Sheets. In addition to the transactions described above, Swire is also a third-party distributor of the Company's brands in certain regions outside of mainland China and purchases products from the Company under the Company's standard third-party distributor terms and pricing. The China joint venture declared a cash dividend of approximately RMB 341,347,000 (approximately US$ 53,330,000 ) in June 2018 to stockholders of record as of June 14, 2018 and paid such dividend in the third quarter of 2018. The Company's dividend share of approximately $ 31,998,000 was received in the third quarter and was eliminated in consolidation. In addition, in September 2018, the Company and Swire entered into an Equity Interest Transfer Agreement ("EITA"), in which the Company commits to buy out the 40% non-controlling interest in the joint venture. The buyout is subject to various terms and conditions, including regulatory approval in China and is expected to be completed in early 2019. As part of the buyout arrangement, the Company has placed approximately $13,970,000 in an escrow account as a portion of the funds needed to complete the buyout in 2019.
