The Baysider floating sunglasses have a timeless, casual design that makes for classic styling on and off the water, in a medium fit with six base lenses, and non-slip nose and temple pads.  Eco-friendly frames are made with TPX material, a low density polymer that's lighter than water, allowing them to float so you’ll never lose your sunglasses again! TPX is also highly durable, flexible, and heat resistant. Flying Fisherman AcuTint® polarized lenses improve visual comfort, enhance contrast and clarity, eliminate annoying glare, and block 100% of harmful UV. The Triacetate lenses are also impact and scratch resistant, and feature an anti-saltwater coating for added durability.
