Looking at the WX Chase, you’d never guess that when worn with the included side shields (both permanent and removable) this lightweight, sophisticated model meets ANSI safety standards for protection on the jobsite. A tough combo of metal and triloid nylon frames, coupled with shatterproof selenite lenses make the WX Chase virtually indestructible, while maintaining a slim profile that’s comfortable enough to wear all day, and stylish enough to wear every day.
