The German outdoor brand Jack Wolfskin, owned by the U.S. company Callaway Golf since the beginning of 2019, is celebrating its 40th anniversary in 2021. To mark the occasion, protagonists as well as customers will be featured throughout the year on www.jack-wolfskin.com/40years, who have shaped and accompanied the brand in its spirit of adventure both then and now. The company’s own 40th-anniversary collection also picks up on the brand’s heritage in revived retro styles, including the Thunderblaze Jacket, a reminiscence of a true classic, the legendary Thunder & Lightning Jacket from 1994. Another groundbreaking classic, the ACS (Air Control System) carrying system, which revolutionized the market in 1991 with its smart ventilation design, lives on today in the Crosstrail Backpack series. The campaign starts on March 3.
