"The Velocity 6.5 Enduro Goggles are designed for extreme enduro conditions, featuring a special ventilated lens developed with Jonny Walker. The CE certified double lens is bulletproof, 170° WideVision, and permanent anti-fog, so you can look ahead with clarity and without fear of roost or loose gravel. An easy clip-in/out system allows for fast lens changes, and the self-draining lower edge helps shed dirt. Outriggers allow your goggle strap to fit seamlessly over a wide range of helmets, and the tapered frame shape even fits helmets with tighter eye ports. The goggles stay comfortable every lap with the removable triple-layer face foam and anti-sweat fleece backing. OTG compatible to wear over prescription classes, plus Roll-Off and Tear-Off ready (tear-off pack included), the Velocity 6.5 Enduro Goggles are built to keep you comfortable on intense all-day rides.
