Each of the 3 "F's" represents a 3F Vision value: feeling, freedom and fun. 3F's goal is to make sunglasses that accompany you on the bike, on holiday, on trekking and in the mountains. In our e-shop, we offer sports sunglasses from the 3F Travel and 3F Sport ranges in a variety of colours, a wide range of lens tints and a UV filter that protects against UVA, UVB and UVC radiation.
