How warm is the Montana jacket?

It has a quilted nylon lining and insulation aimed at midrange warmth, so it handles cool to moderately cold days. It is not a replacement for a sherpa-lined or heavy parka in deep winter.

How does it compare with Carhartt's traditional duck jackets?

The Montana adds Rugged Flex stretch, a pleated bi-swing back and an adjustable droptail hem, so it moves better across the shoulders than a standard rigid duck jacket. The trade-off is lighter insulation than Carhartt's heavily lined work coats.

What is the fit like?

Carhartt lists it as a relaxed fit, so it leaves room for layering over a shirt or sweatshirt. Leaner builds may want to size down.

Does the stretch fabric wear like regular duck?

The shell is 99% cotton and 1% spandex at 12 ounces, so it keeps the abrasion resistance of duck while flexing. Expect it to feel stiff when new and soften with wear.
