Does the Carhartt J140 run true to size?

No. It runs about one size large, and Carhartt recommends sizing down one size from your usual. A 6-foot model with a 40-inch chest wears a medium.

How warm is the Active Jac?

It carries Carhartt's Level 3 warmest rating, with quilted flannel in the body and hood, nylon in the sleeves, and polyester fill. It suits severely cold conditions.

What pockets does it have?

Two large lower-front pockets and two inside pockets. The hood is attached and lined with quilted flannel, with a draw cord.

Is this the same as the J140?

Yes. Carhartt notes the jacket was formerly known as the J140; it is the same flannel-lined active jac.

Engineered For high warmth in severely cold conditions, anyone who works outside can appreciate the cold-weather chops of this men's flannel-lined hooded jacket.
