Recently, I bought a nice breathable jacket for commuting. I got it from a large mail order retailer and they promised it was not only breathable but waterproof and quite warm (down to 0 degrees F.) On my first ride I decided to go a little longer and I noticed the top of my pants was soaked with perspiration. Rather than wicking through the many layers as it should have, it just soaked everything. Talking to customer service was an eye-opening experience. "No one makes truly breathable jackets that warm," said the customer rep. "either they breathe and they don't keep you warm, or you sweat like a pig and don't breathe at all." Has anyone else run into this type of problem when considering winter jackets?
