Marmot Women's Montreaux Down Coat

The Marmot Women's Montreaux Down Coat is a plus-size puffer jacket built for cold-weather days in town or on the trail. Its 700-fill-power down insulation delivers lightweight warmth, while a water-resistant Down Defender treatment adds moisture protection and helps the down retain its loft. A fleece-lined torso, interior cuffs, and handwarmer pockets add comfort where it matters, and the two-way front zipper prevents bunching when you sit and gives easy access to inner layers.

The zip-off hood with removable synthetic fur lets you adjust coverage, and interior zippered and drop pockets keep essentials secure. With a slim fit and a 40-inch center back length, this coat is available in plus sizes 1X through 3X. The shell is made from 100% post-consumer recycled polyester in a plain weave at 71 g/sqm, and the coat weighs 2 lbs 9 oz (1,153 g).
