4EST Shades Floating Wood Sunglasses
They come from the 4EST, but these wood sunglasses have no problem heading to the ocean, lake, or river too. Made from real maple, the wayfarers are lightweight and low-density, so if you drop them in the water, they'll float.
the 4EST floating shades shown here come in 51mm and 55mm lens widths, and Black or Brown Maple woods. Both are funkified with etchings along the temples, and have UV400, anti-reflective polarized lenses.
