Stuffed with 1247 grams of some the best quality down in the world and designed for extreme cold expedition use, the Marmot CWM is a regular on high altitude and polar expeditions. It's constructed with MemBrain® waterproof, breathable outer fabric for outstanding weather resistance and durability. The CWM Membrain is roomy enough to stash essentials like water bottles to protect them overnight.
Marmot do not use the EN EN13537 sleeping bag temperature rating system for either the Col Membrain or Cwm Membrain bags as they do not believe the test to be adequate to produce reliable results for bags of this quality. Instead they rely on a combination of their own tests both in-house and on expedition and their vast experience in designing some of the very best sleeping bags on the planet.
