Its like having 3 sunglasses in 1 These Tifosi Torrent sunglasses feature 3 sets of lenses that allow you to switch out the tint depending on your activity. Featuring interchangeable lenses, frame includes smoke gray lenses and 2 additional sets: clear and AC all-conditions red. Smoke gray lenses and AC red lenses feature Glare Guard coating. Glare Guard reduces glare and decreases eye fatigue while still allowing you to distinguish terrain breaks. Additional lenses are ideal for low- and medium- light to nighttime conditions. Lightweight and virtually shatterproof, polycarbonate lenses are 20 times more impact resistant than glass and one-third the weight. Grilamid TR90 lightweight nylon frames offer a consistent fit and flexibility in all temperatures and are extremely impact resistant. Hydrophilic rubber nosepiece and temple ends become tackier when wet for reliable grip during exercise and hot weather. Fits small to medium faces. Includes a protective case and microfiber cleaning cloth.
