The Vision helmet, the most resistant foam helmet in the Black Diamond range, combines EPP foam, a round of EPS foam and a polycarbonate shell which helps protect you from knocks and bumps, while remaining extraordinarily light at only 210 grams. Improved side and rear protection add a new level of protection that meets UIAA standards while strategically placed vents keep air flowing even in extreme heat. The support system and chin strap give the Vision helmet a sleek style and the integrated headlamp hooks are small so that they do not catch on the shoulder straps and allow you to easily light your way on late routes day.
