I have a pair and am about to buy some more as I think they are great. I think that for men, they are usual sizing. Being of the female type, I had to go up a size as I've got hips (women without hips probably don't need to) but find them really comfortable and far less embarassing to walk around in than the usual lycra tight fitting stuff. They do a great techincal job and also make you feel less self-conscious off the bike - don't think I'll go back to "normal" lycra shorts again. Hope this helps.
