Stay warmer where you need it most with the Pro Thermal Jacket. Constructed from a windproof material and featuring panels of an innovative insulating inner liner with octagonal yarn fibers that are more efficient at trapping heat, the jacket gives warmth without overheating. Open ventilation on the side panels further help control temperature regulation, and a fluorocarbon-free DWR treatment supports protection from the rain. The packable jacket fits into its own pocket and can be secured to a bike, making it the ideal partner for changeable conditions. Other features include elasticated sections on the waist hem and cuffs to ensure the jacket stays in place, a hanger loop and zipped pockets.
