Constructed using a windproof outer material, the jacket features panels of innovative insulating inner liner that use octagonal yarn fibers that better trap heat and ensure moisture wicks away from the body, giving warmth and dryness without overheating. Ventilated panels on the side further support temperature regulation. An environmentally conscious fluorocarbon free DWR treatment gives light protection from rain showers. The Pro Thermal Jacket is highly packable and can easily be taken on any ride. It can be folded down to fit into its own storage pocket, which can then be attached to the bike using the straps attached to the pocket. The wind jacket is optimized for the road cycling position and stays close to the body when leaning forward. Elasticated sections on the waist hem and cuffs give a secure fit. The jacket also includes reflective details, a hanger loop and zipped storage pockets.
