evo.com | Leatt Bike Goggles > Hot days, full-face helmet, no fogging - that's what the Leatt Velocity 4.0 MTB X-Flow Goggles are built for. The fully open upper and lower frame design moves air the way sunglasses do, while the 50mm mesh strap lets air pass through helmet vents even when the goggle is on. Minimal foam placement keeps the sunglass-like feel intact, and a self-draining lower frame lets dirt fall away from the lens rather than sitting against your face. This product may contain chemicals known to the State of California to cause cancer, or birth defects, or other reproductive harm.
