Eco-friendly frame made with TPX material thats less dense than any other plastic polymer and lighter than water, allowing it to float. So youll never lose your sunglasses again. TPX is also highly durable, flexible, and heat resistant. Flying Fishermans AcuTint polarized lenses improve visual comfort, enhance contrast and clarity, eliminate annoying glare, and block 100% of harmful UVA and UVB rays.
