Any recommendations on whether a size 1 or size 2 would fit a guy who's 6'3, 165 lbs. with a lean (okay, skinny) build? I wear 32 in most jeans, but my actual waist measurement is 33 or 34". I primarily hunt in Middle TN, where temps range from the 20's to the 90's during the season, so would need to accommodate all sorts of clothing layers.
