I see a lot of bad reviews on the size/fit on these shorts (both in men's and in women's). I usually wear a medium PI Attack or Elite short (183 lb. 5'11"). So I decided to upgrade to the PRO line for once! Way to constricting! I had to return them and get the next size up (large). Now all is happy in nether-land! The only fault is the sizing of these shorts and having to do the return-a-go-go.
