TYR Hydrolite Goggles By removing non-structural polycarbonate & replacing it with lighter TPR, we've shed valuable ounces & made our lightest unibody frame goggle yet: The Hydrolite. Because light on weight means light on face, the LGHLT Hydrolite Goggles are 15% lighter than any of our other unibody goggles & showcase a leak free, watertight fit. Engineered for both comfort & performance, Our VTS (Varied Tensile Strength) double head strap provides a superior fit, while our glide clip adjustment system allows for quick & easy sizing. Micro-polished clearview polycarbonate lenses provide stunning clarity & anti-fog UV protection make the Hydrolite Goggle a perfect for choice for swimmers of all ages & skill levels.
