The most durable foam helmet in the Black Diamond line-up, the Vision climbing helmet features a fusion of EPP foam, an EPS foam puck, and a polycarbonate shell, which keeps the dings and dents at bay, while remaining incredibly lightweight. Improved side and back coverage add a new level of protection that meets proposed UIAA requirements, while the strategically placed ventilation ports keep the air flowing when temps are high. The suspension system and chin strap keep the Vision sleek, and the integrated headlamp clips are low-profile so they don’t snag on over-the-shoulder slings and allow you to easily light the way on sends that push past the daylight hours.
