short sleeve wetsuits?

I have never seen a triathlon short sleeve wetsuit, just full sleeve or sleeveless.  In the little I know, I'm guessing the main differences between full sleeves and sleeveless is mobility of the shoulder and increased surface area on the forearm.  Without going into benefits of one vs the other, I would think short sleeve would be the worst of both worlds - restricted shoulder, either tight arms or a possible opening for water (read: drag), and no advantage on the forearms.

I would suggest trying out as many tri wetsuits, both sleevelss and full sleeve, and see what works best for you.  Many shops will apply a rental fee towards purchase to help justify trying them.

Good luck.

Im a swimmer, and in my experience, full sleeve wetsuits are the best, as they reduce drag, and make you float like a cork. the main fabric is neoprene, which is a lightweight rubbery material, used in many brand name tri suits. that said, in USA swimming, full body suits are banned, and all suits that have neoprene are banned, and i dont know if USA triathlon will follow suit,(no pun intended), unless its a certain temperature or below, the problem is, is it fair to let, 1 swimmer have it, when 20 others dont, especially if it gives them a better advantage in the pool, lake, river etc?

Yeah, they make short sleeve wetsuits, though they are generally used for surfing, wakeboarding, etc...

I've NEVER seen a short sleeved TRI-SPECIFIC wetsuit though, only sleeved or sleeveless. I personally own a sleeveless, but have never owned a full sleeved, so I can't compare the two.
