A high-performance insulation jacket designed to provide optimal warmth and comfort during intense activities in harsh conditions. Combining Polartec Alpha™ insulation—which offers moderate warmth to keep the cold at bay and excellent breathability for superior moisture management—with a breathable knit fabric, this jacket ensures consistent comfort even during stop-and-go activities. Improvements for field use include a slimmer fit compared to the previous model and the addition of two zippered chest pockets. Its thin profile makes it easy to layer, allowing for versatile combinations with a base layer or other mid-layers to suit any season or weather condition.
Features
・Insulation uses Polartec Alpha™ (72% recycled), offering superior breathability, stretch, and quick-drying properties.
・Breathable outer fabric and mesh lining suppress stuffiness and accommodate high-intensity movement.
・Can be worn across a wide range of seasons, from autumn and spring to the peak of winter, by layering with other highly breathable insulated jackets.
・Soft, stretchy material provides a comfortable fit.
・2 zippered chest pockets
・Stretch binding at cuffs
Materials
Breathable Knit 100% Polyester x Polartec Alpha™ 40 100% Polyester (72% Recycled)
