Kask
Professional free skiers Kaj Zackrisson and Sverre Liliequist set up Kask headwear whilst on a ski tour of the Rockies, and Kask beanies were soon seen on the heads of amateur and professional skiers throughout the best ski resorts all over the world.
The beanies didn't look like anything else ever seen before on the ski slopes, until Kask went from odd souvenir to becoming the smartest thing you could wear in the snow.
