Lightweight, simple and highly functional. When you're ski touring, on the piste or running on forest trails, the Hydropore Beanie from Jack Wolfskin is everything you want from a hat: top-notch functionality and a tiny pack size. Just stuff it in your jacket pocket and pull it out when you need it. You can even wear it under your ski or bike helmet. This hat is made of a stretchy, high performance fabric, which has outstanding wicking performance. So your head will feel dry and comfortable, even when you work up a sweat. The fabric also has a high UV protection factor and a special treatment that helps to minimise odours. That's a lot of functionality for a simple hat!
