Here is another one of my "For What its Worth" replies.

If you are going to wear it in the tree stand over your insulated clothes in colder weather then order your normal size and as has been stated in will easily fit. If however you planned on hunting in warm weather, for example chasing elk up and down the mountains in the early part of the season, you will be sorely disappointed by ordering your normal size. I know in my case I could have one two sizes smaller than what I have and be happier than a hound with two tales.

You may also have to modify your bow arm by trimming some of the "leaves" from the sleeve. I know I had to do that on mine. To keep it from fraying I gingerly touched each piece I cut with fire. Just be very carefull that you don't catch the suit on fire because it could easily happen. All the more reason not to wear this suit (or any other nylon type of leafy suit) by a campfire.
