Marmot made the MenAAAs Mountain Down Jacket with the same warmth-retaining features used in a high-end, cozy sleeping bag. A powder skirt and a long length make this puffy sweet for butt-cold days on the slopes, and MarmotAAAs Angel Wing Movement design lets you move your arms without lifting the entire torso of this jacket. The 650-fill down insulation keeps you toasty, a waterproof breathable membrane comes in handy during ice climbing adventures, and a detachable powder skirt keeps the snow from staging an invasion when the skiing is just too good to slow down.
