They're back. When we did the first edition of our sold-out driving sunglasses, we of course went with an all-black matte frame (because everything looks better in black). When it was time to reissue them, the eyewear gurus at Warby Parker helped us to craft a new Whiskey Tortoise version that's just as handsome as the original. Designed from the ground up for driving, and looking good while doing it, the limited edition Warby Parker x Uncrate Model X1 Sunglasses succeed on both fronts, if we do say so ourselves. Each pair is made with premium acetate and comes equipped with Zeiss Ri-Pel-coated lenses to give you extra protection on the road. The Model X1's curves were inspired by sports cars of the 1960's, and are just as timeless and functional as those beautiful machines. As usual with Warby Parker eyewear, for every pair of Uncrate edition frames purchased, a pair of glasses will be given to someone in need.
