A word in defense of cotton. Summers in the foothills of the Sierra are HOT! and, importantly, DRY not humid. My best summer "jersey" is an old, cotton T-shirt with sleeves and tail torn off and bib shorts. Lots of ventilation. The damp cotton dries very quickly but provides some cooling as it goes. Works for me better than polyester...and keeps my Fred credentials valid and no "farmer tan" which, to all native Californians, is socially toxic.
Fall comes, I go to wool, then wool with a wicking long sleeve beneath, then windbreaker, then jacket....then the cycle reverses itself to cotton T-shirt again. Can't begin to imagine Chipcom and other snow bunny types. Brrrrrrrr!
