The Nitty-Gritty: The Polar Shift jacket from TREW is built for the rigors of the backcountry and keeps you warm when you need it and easily tucks away when you don't. From The Brand: Outer layer. Mid-layer. Double-sided. Quadruple useful. The reversible Polar Shift Jacket is insulation at its best: lightweight, durable, packable, and warm. Its buttery-soft face fabric slides easily under shells and over baselayers, and its PrimaLoft® ONE laminate is as thermally efficient as down, yet maintains its loft when wet to ensure your body will remain functional regardless of forecast errors. When not shielding your body from the cold, the Polar Shift prefers to nestle quietly between the shovel and water bottle in your backcountry pack, ever at the ready. If you never leave home without it, you’ll be that much more prepared for whatever lies ahead. — • Ultralight 15-denier double-ripstop nylon shell • 60g PrimaLoft® ONE Insulation • Diamond quilting pattern secures the insulation • Insulated hood • Convenient chest pocket • Insulated open-access hand pockets • Interior drop-in storage pockets with elastic opening • Elastic cuffs with thumb loops • 12oz • Fully reversible This item is for final sale only and non-returnable.
