Perfect for a next 18 holes or a relaxing day on the beach the 
Tifosi Duro provides full frame lenses with a frame that is tough as nails. Made from a homo-polyamide nylon called Grilamid TR-90, a light, durable material with a high resistance to UV and chemical damage, the 
Duro is designed for the rigors of the course, without sacrificing style. Their vented lenses prevent the sunglasses from fogging up and aids in keeping you cool.   Included are three interchangeable lenses, Brown, Golf/Tennis, and Extreme Contrast. 
- Polycarbonate Lenses
 - Optically Decentered: eliminates distortion and magnification
 - Adjustable nose pads customize your fit and limit slipping

For heavy-hitters on the course and off, the 
Tifosi Duro will have you looking good and performing at your best.
