I started using polypro's after talking with my girlfriends brother. He is a crabber in Alaska and swears by them. They are light weight and warm. Also the poly pros will wick the moisture away from the skin and keep you from getting all sweaty. If the morning is cold, it is not good to get sweaty , as when you sit down you will get cold. If I am going to hunt a mile or so from camp, I will wear my shorts to hike to the spot and then put my heavier clothes on when I get there. It is a little cold to start, but some brisk walking will warm you up quickly.
