The Leatt Velocity 6. 5 Enduro goggle is an MTB goggle with a ventilated, bulletproof double lens that moves air behind the lens. The 170deg WideVision field keeps the view wide, and permanent anti-fog protects the inside of the lens. What Our Gearhead(R) Experts Are Saying:"By the fourth lap the fleece backing has soaked up my sweat, so it isn't running toward my eyes. The foam still feels comfortable on my face, even after a full day of riding."
