Dirty Dog sunglasses have evolved since the discovery of TR90 Grilamid - a lightweight and virtually unbreakable compound. They are designed to fit snugly around the face providing optimum comfort and maximum protection from glare. Decentred lenses for optimum visual performance are made from polyfilter polycarbonate, a virtually shatterproof material which blocks 100% of UV rays.  These materials allow the design of contemporary styles without sacrificing strength or performance. When an athlete is pushing their body to the limit, they can be confident their eyewear is not going to fail them. Remember all our prices include free UK P&P.
