The 
Tifosi Watkins uses 
Swivelink technology to provide you two pair of glasses in one. With exchangeable lifestyle and sports arms, there is no longer a need to switch between multiple pairs of eyewear. Made of a homo-polyamide nylon called Grilamid TR-90, a light, durable material, with a high resistance to UV and chemical damage, the 
Watkins will hold up to anything you can throw its way. And with hydrophilic ear and nose pieces, these glasses will stay in place during the hottest of days.
- Polycarbonate Shatterproof Lenses
 - Optically Decentered: eliminates distortion and magnification
 - Swivelink arms adapt your eyewear to any activity in your active life
 - Case and cleaning cloth included
 
The 
Tifosi Watkins is the ultimate solution for your active lifestyle.
