The Carhartt Men's Gilliam Vest is a synthetic insulated vest for cool to cold weather. Sit yourself up in the deer blind or go for a hike in the woods and the 100 gram polyester insulation will toast your core. Wear it over a base layer or other long sleeve, leaving your arms with the freedom to move without overheating. The exterior Cordura shell has a Rain Defender finish, so an unexpected light sprinkle won't soak in and ruin your day.
