When winter temperatures really start dropping, the Marmot Men's Guides Down Vest offers additional core warmth to keep you nice and toasty. This vest 700 fill down insulation is light, lofty, and highly compressible, and is treated with water resistant Down Defender so it doesn't clump up and stop insulating if it's exposed to moisture. The durable polyester shell and lining have water resistant coatings as well, so you're doubly protected against wet weather. The Guides Vest features a smooth DriClime lined chin guard for against the skin comfort, and a wind flap behind the front zipper seals out blustery weather so you don't feel a chill. An elastic drawcord at the hem keeps in warmth. And two handwarmers have a soft interior to keep you hands cozy as well as warm.
