A high-performance insulated jacket that excels in intense activities under harsh conditions. By combining Polartec Alpha™ insulation, which offers both warmth and excellent breathability for superior moisture management, with a breathable knitted fabric, this jacket provides consistent comfort even during stop-and-go activities. Compared to the previous model, the fit is slimmer and it features two chest zip pockets, further enhancing its usability during activities. Its lightweight and layer-friendly design allows for diverse layering patterns depending on the season and weather, such as wearing it alone over a base layer or combining it with other mid-layers.
Features
・Uses Polartec Alpha™ (72% recycled) for insulation, offering excellent breathability, stretch, and quick-drying properties.
・Breathable outer fabric and mesh lining suppress stuffiness and accommodate high levels of activity.
・Can be worn from autumn and spring to mid-winter when combined with other highly breathable insulated jackets.
・Soft and stretchy for a comfortable fit.
・2 chest zip pockets
・Stretch binding at cuffs
