Story A versatile outer layer with a smart fit, performance features, and two ways to wear Proof’s technical apparel is built for versatility—each piece is designed to be ready for anything, whether that means the perfect amount of stretch to sprint and catch a train, or a DWR finish that fends off the coffee you spill on yourself sliding through the closing doors of said train. The new Reversible Shirt Jacket keeps that mission alive with a laundry list of performance features and the ability to transform from outdoor puffy to happy hour layer at the drop of a hat. Insulated with a lightweight, chill-fighting poly fill and fitted with premium snaps and zippers throughout, there’s a whole lotta value packed into this versatile, stylish shirt jacket.
