The Lagoon features a timeless design for classic styling on and off the water. Fit is medium with six base lenses. Eco-friendly frame made with TPX™ material that’s less dense than any other plastic polymer and lighter than water, allowing it to float. So you’ll never lose your sunglasses again. TPX™ is also highly durable, flexible, and heat resistant. Flying Fisherman’s AcuTint® polarized lenses improve visual comfort, enhance contrast and clarity, eliminate annoying glare, and block 100% of harmful UVA and UVB rays. The Triacetate lenses are also impact and scratch resistant and have an anti-saltwater coating. This combination makes the new Floaters™ incredibly comfortable for all day wear.
