Pro alpinist Fabrizio Zangrilli uses the ultralight Marmot Helium MemBrain 15-Degree Sleeping Bag to stay warm and dry at the top of the world, so odds are that this down sleeping bag will work for you, too. Marmot’s waterproof breathable MemBrain construction repels snow and water while expelling perspiration so you can take full advantage of the toasty down insulation without worrying about it clumping and leaving you high and wet.
