An extra hit of heat in an extra-light package.

At just nine ounces, the Mountain Hardwear Men's Nitrous Down Vest has just the right amount of goose down insulation to warm your core when you're on an ice climbing route, hunkering down on the trail, or enjoying deliciously deep powder on your skis. Thanks to the relaxed fit, you can easily pull this vest over a thick next-to-skin layer and, when things heat up, just whip off your vest and pack it away in its own pocket for easy storage.

  • Quilted pattern makes sure the goose down stays in place
  • Micro-chamois-lined chin guard won’t disturb your windburn
  • Hem drawcord tightens the Nitrous so no frigid air creeps in while you climb or attempt to sleep
  • Vest stows into its own pocket for easy packing in your touring bag or backpacking pack
