Nutterbuster: I'm all of about 5'9" and 200 lbs. My waist is a tight 36" Not exactly huge but not tiny either. Funny about the diaper comment. Would the Kestral #2 fit me??? The waist sizes on their website are such a huge variation. I'm closer to the Number 1 but perhaps a little over with hunting clothes on etc. Not that I've decided to buy that model but was just looking at the sizing yesterday on their website.
Get the size 2
