8,000 Feet or 8,000 Meters

For the coldest conditions and longest expeditions, the Big Agnes Cinnabar -20 Down Sleeping Bag is a must-have piece of equipment. It might be tempting to shave weight by going with a less burly bag, but when you're fast-asleep at base camp and your partners are struggling to keep their teeth from chattering, you'll be glad you brought it along. Stuffed with water-resistant, 850-fill down, the Cinnabar takes its insulation seriously. Specially made to let you change clothes while staying in your cozy sleeping bag, Big Agnes still found a way to cut weight through the use of a modified mummy design. The beefy Pertex Quantum Pro shell fabric is reliable through harsh conditions and years of use, meaning you can take on peaks ranging from 8,000 feet to 8,000 meters knowing that you always have a cozy, warm bag waiting for you in your tent.
