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. Cross-baffle construction keeps down from migrating and the wrap-around footbox traps heat ultra efficiently and lets your feet sit comfortably. The CWM comes with a drawcord hood with easy-grab cords, a warm down-filled neck baffle, and zipper draft tube to seal up all the gaps against the unrelenting cold and make sure all your body heat stays close, where it belongs. The draft tube also sports a hidden pocket so you can access small gear without having to unzip in the middle of the night, and Marmot included both stuff and storage sacks so you can bring your bag along and make sure it stays lofty when you're off on more summery adventures.
