Carhartt J130 Washed Duck Active Jac vs Carhartt Flannel-Lined Active Jac J140

Both are Carhartt's warmest-rated active jacs in 12-ounce cotton duck, so the choice comes down to insulation and lining. The J130 uses 80g 3M Thinsulate with a quilted nylon lining and Cordura-reinforced sleeve hems; the J140 uses quilted flannel through the body and hood with nylon in the sleeves, plus Wind Fighter. Owners rate the J130 highly for hard outdoor work in cold, dry conditions. Pick the J140 if you want a softer, warmer-feeling interior and better wind blocking for standing around in the cold.

• Choose the J130 Washed Duck Active Jac if you work outdoors in cold, dry weather and want lightweight Thinsulate warmth with reinforced sleeve hems that resist wear.
• Choose the Flannel-Lined Active Jac J140 if you want flannel against your body and in the hood, two inside pockets, and Wind Fighter for windy days.
