Try our new TR-90 flex sunglasses. These glasses are they same style as our previous polycarbonate sunglasses so you can keep enjoying the style you love. All glasses have polarized lenses so your eyes are protected in any adventure. The difference between the TR-90 Flex and your typical plastic sunglasses falls on the flexibility of the plastic. Not only do the glasses flex under pressure but if the arms pop off just put it back and carry on your way no more bent screws.
