How does the denim weight compare with Carhartt or Dickies bibs?

It is heavy-weight cotton denim, in the same rugged class as traditional Carhartt and Dickies bibs. It is not stretch denim, so expect a stiffer feel at first that softens with wear.

What pockets do these overalls have?

There is a 5-in-1 bib pocket, a rule and slide/cell pocket, a pocket watch pocket, and a hammer loop. That covers tools, a phone and small items without a separate tool belt.

Do they have a zipper fly?

Yes, the fly is a zipper unless a specific variant is noted otherwise. The bib front closes over it as on standard overalls.

Are they good for hot weather?

Heavy-weight cotton breathes better than synthetic work pants but is warmer than lightweight denim. They suit three-season work; in high heat, lighter bibs will be more comfortable.

How should I size them?

Overalls are cut to be worn over a shirt, so pick your usual bib size rather than sizing down. Heavy cotton denim has little give, so check the brand's measurements if you are between sizes.
