“Instead of wearing those old long johns, try wearing good comfortable sweat’s top and bottoms. You can wear two pair if it is really cold, 20 degrees or so, and the sweats will keep you warmer than any other underclothing. One thing I like about wearing sweats is I can still move around.”
Editor’s Note: Thanks for the tip Frank. It will be nice not having to listen to my wife complain about the holes in my sweats out on the boat!
