The Truewerk Woobie is an extremely light and flexible work hoodie. (The name is inspired by the military-issued poncho liners called “woobies.”) It can be worn on its own in moderate weather but is specifically designed as an insulating mid-layer; both the shell and lining are made to stretch, allowing some freedom of movement. According to Truewerk, the exterior is abrasion resistant and water repellent, while the interior is designed to wick moisture away from the body. The Woobie hoodie is $140; it also comes as a vest for $100. Both are black. truewerk.com
