I'm 6'3 and nearly 300 lbs with a 44" waist. I ordered the 3X. I wanted them a little big in case I wanted to wear them over pants. They are snugger than what I was expecting from a 3X, They fit like a 2X. Still very useful for me. The other issue is that the suspenders are a little short. Even full extended they was nug in the crotch. If they were an inch or two longer, these would be about perfect.
Great bibs. Used them on a cold Iowa whitetail hunt last weekend and they did fantastic. Love the dual full length side zippers to get over heavy boots. Also did not have to pick burrs off of them like my last pair (not game hide brand).
Wore the for the first in the field this am. Was 17 degrees in Northern WI. this am. For the Wiso deer opener. Very warm. And quiet..
Great fitting warm bibs!
