Carhartt Coverall Sizing?

I had some Carhartt x01’s several years ago that I unfortunately lost, but I don’t remember what size they were. I’m 6’1 and about 165lbs. Does anyone have any size suggestions so that they fit nicely after cutting out the lining? Obviously a little baggy wouldn’t be a bad thing

I use 46 long. I’m 6-3 190lbs. With the lining removed you get more space.

Do you think reg would be too short for me at 6’1?

Probably be ok. I’d say 5-10 to 6-1 is regular buddy
