The Leatt Velocity 4. 5 MTB goggle suits smaller helmets and junior riders. Its open lower frame drains on its own, so dirt falls away from the lens, and dual-layer face foam with anti-sweat fleece backing keeps the fit comfortable. What Our Gearhead® Experts Are Saying:“I wear these with a smaller helmet, and with no outriggers on the frame, nothing sticks out to fight the shell at the edges. My glasses fit under them too, so I don't swap eyewear before a ride.”
