Subject: RE: non wetsuit legal IM - swimAfletcher - 2009-08-06 9:49 AM I wear sweatshirts year round! Inside in the summer is the worst because people crank the AC to ridiculously COLD temps (72). Then you go out and it's 10 degrees warmer then go back in and it fels like it's sub zero. Around here, make that '30 degree warmer'.  To OP: I hear they improve speed, and according to a video on this site, they provide some minimal buoyancy as well, at least according to how the testers felt, if I recall correctly. But I can't imagine that you're going to want WARMTH at IMLou. I think the river temps are generally pretty high that time of year. If anything, we will be looking for ways to keep cool! |
