While I was wearing them on the beach in the sun, they literally snapped in half. I thought a seagull hit me in the face or something. Nope, I don't know how and I don't know why, but they just snapped. Maybe the sun heated them up? I don't know. I wasn't injured at all, and this seems like a fluke because all the other reviews seem to have no issues.<br /><br />Other than that though, I thought they were great, if not a little cheap. I got the Black Crimson ones and on the side there is a logo that says &#34;ZeroUV&#34; in red letters. Pretty minor, and only on one side.
