The WX Contend is truly a force to be reckoned with, combining its popular rectangular lens shape with an ANSI Z87.1+ safety rating for optical clarity and protection against high-mass and high-velocity impact. Light as a feather and tough as nails, this model sports a false keyhole nose bridge and subtle design elements baked right into the snap-hinge temple arms. The high-wrap WX Contend is protection, comfort, and style, wrapped into one pair of sunglasses you’ll want to take on all of your adventures.
