I work in the oilfield and can only wear these during the coldest days. If in the 20's, I'm getting hot pretty quick. Mine have been awesome and have zero flaws. I am 5'9, 190/195 and wear a medium short. I will say after washing for 2 years, they do shorten up.

Very unhappy. Zipper broke second day and carhartt won't get back to me

These were great when we first got them. Very warm. But after one wash, the zipper on the busted and is missing some of the little metal piece the zipper goes one.

My grandson who works for BNSF Railway loves them.Said he started warm and toasty while he walked the track at night.

If a person wants warm well made coveralls there are probably none any better.. The main couple things I didn't like I am gonna list because if a person was to need a piece of clothing like this they will probably be outside a lot no doubt and have them on most of the time. The pockets up on top of the bib are useless there to small to get your hand in. The fact they zip all the way up may be why they are so warm. But this is heck when you need your wallet or have to go to the bathroom either wont be done quickly. As well along the sides and waste line there are no buttons or splits to make these actions any faster. The bib zipping all the way up helps with straps not falling off your shoulders.. if these were made like some of the uninsulated overalls with straps they may be better.. it's nice to have a store a person can go in and try on than ordering online but I guess that's of days passed
