I have been using a riding jacket but it is a bit hot during summer over long trips. I like the jacket because it is very simple, only one pocket for a key and it protects in accidents (or so I think).
I have now used a so-called "technical t-shirt" used by footballers and armies as underwear. It moves the moisture out of the skin so my body temperature is more stable even with the jacket. I have replaced my cotton t-shirt under the jacket with it and I feel much better with it. I am unsure why but it works, ideas about such layered bicycling welcome.
I have been considering to buy this suit here but I have no experience with them earlier. What should I look for with this kind of suits? And how do layers work here? Which layer moves the moisture, not to get cold etc?
