The low-profile Racespex Mirror Goggle is ideal for outdoor racing. The frame adjusts at the nose bridge to create the perfect fit and has flared silicone seals for comfort. Mirrored lenses are ideal for bright conditions, including direct sunlight, because they reduce glare from the sun and off the water. Additionally, Fogbuster anti-fog coating controls moisture and keeps the lenses clear. All Zoggs goggles feature safety-tested UV protection against both UVA and UVB rays. Just pull the two back straps to tighten the Easy Adjust silicone double band strap. Comes with four nose bridges in different sizes and adjusts to fit any size head.
