The Wind Warrior was developed for people who use eyewear during activities when more protection from the wind is needed. The billet frame design has features of a sunglass and a goggle eliminating the need for a strap to hold them on. Ultra soft dual density foam and the bullet air vents direct air away from the eyes relieving eye irritation and preventing fog. The quick-change lens system allows the wearer to switch out the 100% uva, uvb protective hard coated polycarbonate lenses to suit different lighting conditions. The Wind Warrior looks awesome and is one great performer whether you're out cruising on your motorcycle or snowboarding in the mountains. The Chrome lenses are dark enough for day time use, but not recommended for night time use. Yellow replacement lenses are available for night riding.
