100% UV protection Impact-resistant polycarbonate Victory? lenses High-quality Grilamid frames Signature patented Scoop Venting SystemHytrel rubber nose pads and temple tips Ascend to alpha male status in a pair of SPY Alpha Polarized Sunglasses. These virtually indestructible shades are outfitted with shatterproof polycarbonate Victory lenses that provide 100% UV protection. Ultra-tough Grilamid frames sport Scoop, a venting system that combats lens fogging by promoting airflow by forcing air through strategically placed vents. This feature is no gimmick; it really works, and is especially helpful when you're sweating up a storm. The Alpha also has Hytrel rubber nose pads and temple tips-which get tackier when moistened-to provide a secure, comfortable fit.
