Sweat Jacket, too big for me. Warmest level of Carhart. NWOT. Worn once. Description Warmth Rating Earned: Level 3 - Warmest Engineered For High Warmth in Severely Cold Conditions. See Technology section below for more details. Work or play, when the weather turns damp and windy, this men's Super Dux® insulated jacket keeps you warm and mobile. It's named after the original Carhartt hunting gear from the 1930s, but it features modern insulation and a lightweight, low-profile feel that flexes for an unrestricted feel. Back pleats and underarm gussets make sure you always have room to swing an axe or reach over your head. It's also wind-resistant, sheds light rain, and is more abrasion-resistant than our traditional duck canvas. An adjustable hood and plenty of pockets make sure you're always prepared
