Lightweight protection with a great fit and comfort, too. With Kaj's favourite helmet, you can take on any challenge, no matter how steep the slope. Our Sinner Serfaus is a hybrid ski helmet. The perfect combination of a lightweight In-Mold-helmet and extra protection thanks to the shell with ABS technology. The soft fleece lining on the inside can be removed and washed: a good thing after an intensive day on the slopes. Serfaus has a double adjustable ventilation, goggle holder, quick release buckle and a handy size adjustment system so you can always find the perfect fit.
