Love these!!! Here's some info about the sizing for yall!
Hey guys I wanted to let you know this about the sizing. I'm 5:11 I weigh about 200lbs. I originally got the XL REG and they were about 5 inch's too long on the legs and super baggy in the chest area all the way adjusted. I sent them back and ordered the XL short and they were good length wise and baggy wise. I wear these over my company uniform in the winter so a little loose is perfect. The XL short is basically a 44 x 32 in the old carhartt sizing. The new sizing of XL reg is way too long in the legs I'd say for most 5:11 guys and I'd bet unless you got a beer belly they would be too baggy too lol. Anyway I just wanted to try and save someone the headache of having to mail back an order. The new pair are made different from my older pair the inside lining on my old ones are red quilt lined and the new are a thinner black. I will say the area around the boots on my new ones appear to be made thicker than my old ones.

Straps too long
I like the coveralls, but the shoulder straps lacked sufficient adjustability. Had to have them shortened at local seamstress.

Small sizing.
Ordered a 3xl regular, I have a 46-48 waist depending on brand. These were so tight with jeans on I thought they would rip. I didn't dare try and bend ot kneel down with them. Go up at least 1 size more before you order.
