I recently decided I wanted a pair of floating sunglasses. I was surprised how few reviews there were for the brands I found. Luckily, I found these sunglasses in the store after having researched them online. I have been very please with them. The optical clarity is equal to the Oakley polarized lenses I have been wearing for years. The frames are comfortable and they do float as advertised (tested in a pool before taking them to the beach or lake). The warranty seems pretty awesome as well, (lifetime repair + 1 loss per pair) but I haven't used the warranty service so I cannot attest to its ease/efficacy. Overall very happy with these glasses. They seem to be in the same optical realm as the Oakley and Maui Jim composite lenses, but these have the bonus of floating + better warranty.
