The wind races in from the Patagonian icecap with such unimaginable velocity that even a Easy Path run can seem daunting. But the magic of the place lures you in, so go prepared. The Boys's Wind Shield Jacket's stretchy, revised polyester fabric is significantly lighter, with superb compressibility and softness, and is laminated to a polyurethane film for full windproofness. A nonlaminated breathable polyester/spandex brushed fleece covers the underarm panels and cuffs (which have fold-away thumb loops), and a Deluge DWR (durable H2O repellent) Complete sheds light precipitation. Jacket details include a brushed fleece collar for next-to-the-skin comfort, full wind flap and zipper garage, slightly dropped tail, two zippered handwarmer pockets and a rear center-back pocket with a reflective zipper and interior cord pass-through. Reflective logos on the left chest and center back.
