Mountain Hardwear Men's Sub Zero Down Jacket

A dependable climbing jacket is as essential as a reliable mountaineering rope. A four-season mountaineering shelter can save you from the elements and a -40F rated sleeping bag can provide adequate warmth, but it's your outerwear that's going to protect and insulate you all the way back to civilization, which is why this 650-fill down Sub Zero Jacket is an essential fit for expeditions and extended climbs. You'll find reinforcement fabric along key abrasion areas of the garment and external pockets for your gear. This is expedition-quality protection for severe winter weather and high altitude conditions.
