Lens: Clarity lens by Carl Zeiss Technical Features: contrast-enhancing Clarity lens, optimized for large field of view Frame: ventilated, flexible frame construction Strap: adjustable Recommended Use: downhill, enduro Like its name suggests, the POC Ora Clarity Goggle maximizes your visual contrast and field of view when you're hurtling down a mountainside on the downhill course, plunging over rock rolls on freeride terrain, and clearing doubles in the bike park. The Clarity lens by Carl Zeiss provides greater visual acuity and contrast through a wide variety of conditions, ranging from bright, sunny days to low lighting in the forest. The flexible frame design conforms to your face and won't break upon sudden impact, plus it's ventilated to prevent the goggle from fogging once you start to sweat.
