The perfect garment for active use in cold, wet environments. The Stretch Alpha Jacket combines the warmth and moisture transport of an insulating layer with the durability and mobility of a softshell. The jacket is built out of three layers; starting with a grid fleece that pulls moisture away from the body towards a layer of Polartec® Alpha® Insulation. The Alpha® Insulation traps and retains body heat while continuing to transport moisture to the outer shell where moisture spreads and evaporates. The final layer is a flexible 4-way stretch woven fabric that is highly durable and protects you from the wind and rain. Wear the Stretch Alpha Jacket if you need to stay warm, dry, and protected while on the move.
