Get some shut-eye in the death zone with a little help from the Marmot CWM -40 Degree Down Sleeping Bag. This 800-fill goose-down-insulated bag is built for the coldest, harshest weather on the planet, from the South Col to the South Pole. Its waterproof, breathable Pertex Shield 2L laminate prevents rogue bits of water, tent condensation, and melted snow from clumping your down and ruining your sleep (and chances of summiting tomorrow). The outer fabric itself is made from rugged 30D nylon ripstop and the lining from 30D nylon ripstop Pertex Microlight, which has a soft feel and the durability to prevent feather leaks.
