I had this brief in my drawer for over a year and forgot about it. Recently I swam front crawl exclusively in another 1" Solar in open water and discovered I had a crisp tan on my backside. I'll be using this brief exclusively for tanning on the beach after my daily runs to get a complete tan. Too bad I can't swim backstroke in open water as well as I do front crawl. Oh well, I guess. I just want to add that the Solar 1" offers the best in comfort for overall fitness swimming. The leg openings fit perfectly where it counts for swimming one's best.
