The MILLE GT Winter Jacket is engineered for that stretch between fall and deep winter, where a breathable, medium-weight insulating layer that shields you from icy winds and precipitation is just the ticket. The front panel is constructed using our NEOS Medium, which is a 3L softshell with PU bonded membrane. Highly breathable, waterproof, insulating, and 100% windproof, this flexible house-developed textile ensures your core stays fully protected from icy winter air, road spray, and rain. The tops of the arms and upper back received NEOS Light, which scales back insulation in favor of boosted breathability and lower weight. And to keep you from overheating as your effort levels rise, the underarms and back use our brushed bi-stretch RX material. The result of these strategically placed textiles is a jacket that's optimized not only for cold winter conditions, but also for your body position on the road bike. In the back is our Triple Ramp Pocket system that locks in your cargo, the winter (3/3) climaCode graphic on the upper panel, and reflective strips on both sides of the center pocket. As with all apparel in our MILLE line, the Winter Jacket is cut in our smooth, layer-friendly regularFit.
