These goggles are great for active and fitness swimmers. A wide field of view and clear lenses provide excellent visibility. Polycarbonate lenses have anti-fog treatment and UV protection, which means that the goggles are also suitable for open water swimming. The comfortable and snug-fitting glasses are equipped with an automatically adjustable nose bridge, TPR seals and a silicone head strap. The headband made of silicone is two-piece at the back, so it stays well in place. A quick adjustment on both sides of the lenses.
