Tifosi Optics' Polarized Just Sunglasses aren't just another pair of sleek sporty sunglasses. True Polarization embeds polarized material into the lenses, instead of applying a coating that will wear off over time. These lenses eliminate glare, UVA, and UVB rays for long lasting sun protection and crystal clarity throughout your workouts. A vented design makes sure the lenses don't fog up mid run, and the durable TR 90 frame material stays strong yet bendable for long lasting comfort. Hydrophilic temple pads make sure the glasses don't slide down your sweaty face, and adjustable nose pads ensure a secure fit.
