I decided to give BARE exowear a try on a trip to Key Largo. The water temp was about 85 degrees-- wow, that's a swimming pool- and a rash guard was all that was required, but I do tend to get cold after multiple dives, and I wasn't sure about thermoclines, so the extra layer of protection seemed prudent. I also like a little protection from gear webbing and inadvertent scrapes against rocks, coral, boat ladders etc. The shorts and vest combo was perfect. Minimal, if any effect on buoyancy, much more comfortable diving and between dives than a wetsuit. I forgot I had it on, and diving in that warm, clear water was amazing. It's also easy to rinse, hang to dry, and pack. Too soon to tell, but the stuff seems durable. I do wish BARE offered a pocket option for the shorts- not huge tech-type pockets, but something moderately sized- hold a reel /DSMB, or extra flashlight, small slate, etc. That would give them SIX stars!
