For bib overalls: Order overalls 4 inches bigger in the waist than your regular pant waist. Since bib overalls run long and have a long rise you also may want to order them 2 inches shorter in length than your regular pant length. (((Example: Your normal pant size: 30 waist x 32 length. Order bib overall size: 34 waist x 30 length..* these run short already as a 30"!!!if ur man wears a 30W x 32L THESE WILL FIT!!))) these are NWT ( tag not attached) never worn.ARCTIC ARE WARMER THAN REGULAR LINING.PREMIUM BIBS!! remember you will have a T-shirt and probably a flannel or thermal shirt under these!
