The Trenton isolé Jacket is highly versatile, warm and durable. Taffeta lining, 100% sealed seams and Lycra wrist gaiters block out the cold, while pit vents help keep you cool when it heats up. An external-access music pocket with headphone port and interior mesh pockets take care of the modern details. Sustainable construction methods are highlighted by the Trenton's Recycled Nylon Canvas fabric and Recycled Polyfill insulation.
