I just got some Cool-Max (tm) shirts which claim to work in cold and hot weather by wicking. They seem warmer to me than my usual 'Stanley Kowalski' undershirts. By wicking away moisture are you not diminishing evaporative cooling? Sweat is our friend this time of year (we got up to 99 F (310 Kelvin) in Portland this week). *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced outside PaddleWise without author's permission Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************

I hated the shirt it felt like it didn't breath and that it was warmer than my usual t shirts. I recently bought a coolmax clone shirt and did an 11 mile race in it on a hot day and didn't notice it pro or con. Which in my mind was a good thing. kirk *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced outside PaddleWise without author's permission Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************
The August "BackPacker" magazine has an interesting article on seating. One concept that was new to me was: "People who put out a lot of sweat are inefficient sweaters." says Robert Murray, direcotor and lead researcher of the Gatorade Sports Science Institute. "Most of it falls to the ground and doesn't do them any good." It would seem that a tight fitting (key) coolmax shirt would move the sweat to the surface of the shirt where it would evaporate and cool the wearer more efficiently than cotton. It takes a lot of sweat to get a cotton shirt damp. The popularity of Coolmax among bike racers would seem to bear this out. . If you wear your shirts loose it probably doesn't make much difference since the air circulating between the shirt and your body would directly evaporate the sweat on the body. I'll save my coolmax for winter layering. YMMV On Thu, 29 Jun 2000, E. Sullivan wrote: > I just got some Cool-Max (tm) shirts which claim to work in > cold and hot weather by wicking.
