For more than 40 years, outdoor and lifestyle apparel brand Jack Wolfskin has had a trailblazing spirit and reverence for nature that was inspired by the Jack London novel The Call of the Wild.

Ever since founder Ulrich Dausien introduced a line of utilitarian performance jackets in 1981, Jack Wolfskin has been a relentless innovator in outdoor apparel and gear such as tents, backpacks, and performance footwear.

Jack Wolfskin continues to innovate, with this new line of outdoor apparel made with brrr° cooling fabric that helps keep you cool and dry and more comfortable wherever life takes you.

Jack Wolfskin’s brrr° collection includes a short-sleeve functional t-shirt and technical tank for men, and lightweight hiking shoes.

The women’s collection features a short-sleeved hiking shirt, short-sleeve technical t-shirt, and lightweight hiking shoes.

brrr° cooling fabric has natural cooling minerals, active wicking, and rapid drying technologies that work together to create a “Triple Chill Effect.” brrr° fabric instantly and continuously draws heat and moisture away from the skin to keep you more comfortable and confident outdoors, indoors, and everywhere you go.

Every brrr° fabric is independently lab tested and proven to outperform other brands. Learn more at
