I have the Carhart bib and a Schmidt coverall. I prefer the bib with a nice heave hooded sweatshirt. The one piece is a all or nothing and can be a pita to remove. If a bib does not fit snug enough for you, you could either spin the shoulder straps or cross ghem behind your back.i tend to like mine a big loose on my shoulders so they don't feel like they are pulling when I sit or get in and out of a truck.
