These rarely discounted Neck Crank sunglasses feature TapOut's revolutionary Heliospheric polarized lenses. You've never worn a pair of sunglasses that perform like these TapOuts. The lightweight, impact-resistant optically-correct Heliospheric polarized lenses reduce unwanted glare by blocking out all angles of scattered and reflective light from snow, water & urban landscapes. They block out 100% of harmful UV-A, UV-B and blue light too. Also features TPR nose and temple grips that resist oil and sweat, thermo-carbonate frame that retains its shape and flexibility in any weather conditions, hand-tooled acetate frames for unique style and vibrant color, wire-injected temple cores and 5-barrel revolver hinges for comfort.
