We love getting out and enjoying nature while getting our athletic fix on clear sunny days. About the only thing we think we could complain about with all that sunshine is blinding glare, either off of a watershed while on the trail or car windshields on the road. Here to save the day is the Slant Photochromic Sunglasses by Suncloud Optics. These medium-fit frames feature a slim, head-wrapping fit that's ideal for outdoor adventurists seeking a pair of sunglasses that won't slip or create pressure points. Megol nose and temple pads keep these glasses put even when you start to sweat. The Grilamid frame is durable enough so you can stuff them in your pack, helmet vents, and jersey pocket without fear of them breaking.Injection molded polarized polycarbonate lens keeps these glasses exceptionally light while cutting glare and harsh sunlight on the brightest days. The photochromic lenses automatically change tint based on light conditions so your vision remains consistent as you bounce in and out of tree-lined singletrack. A bonus set of Rose lens for heightened contrast in low-light conditions as well as a microfiber bag and zippered case are also included.
