The Leatt Velocity 6. 5 Desert goggles block sand and dust with face foam made from sealed EVA instead of mesh foam. Removable triple-layer, dual-density foam with an anti-sweat fleece backing keeps the fit comfortable, and an open lower frame drains on its own so dirt falls away from the lens. What Our Gearhead(R) Experts Are Saying:"I wear these over my glasses with a helmet on, and the outriggers keep the strap where it belongs at the edge of the shell. The tapered frame clears the eye port on a tighter helmet, so the goggle sits in place."
