When the autumn winds drive the sightseers out of the canyon the Marmot Afterburner Jacket keeps you on the trail with Gore's WINDSTOPPER® fabric. The Afterburner’s broad appeal belies its alpinist roots: climber-friendly design, WINDSTOPPER® fleece fabric and precise fit make it equally at home at the crag and on the street. Blustery days won't deter the Afterburner Jacket. Designed to fit over a light layer, the Afterburner comes in handy as a just-in-case insulating layer or a around-town piece. Nylon reinforcements along the sleeves and shoulders cut down on friction when layered and add increased durability. The Afterburner's alpine-style zippered hand-warmer pockets give you easy access to your smaller items when you wear a pack.
