A high-performance insulated jacket that provides optimal warmth and comfort during intense activities in harsh conditions. Featuring Polartec Alpha™ insulation, which offers moderate warmth without feeling cold and excellent breathability for superior moisture management, combined with a breathable knit fabric, this jacket ensures consistent comfort even during stop-and-go activities. The fit is slimmer than the previous model, and with two chest zip pockets, its utility for activities has been further enhanced. Its thin construction makes it easy to layer, allowing for diverse layering patterns depending on the season and weather, whether worn alone over a base layer or combined 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 prevent stuffiness and support high-intensity movement.
・Can be worn from autumn and spring to mid-winter by combining with other highly breathable insulated jackets.
・Soft, stretchy, and comfortable to wear.
・Two chest zip pockets.
・Stretch binding at the cuffs.
