Mountain Equipment Xero 300

Retailers' Descriptions

Here's what other sites are saying:

Made with weight being a primary concern in the design process, the Mountain Equipment Xero 300 Sleeping Bag is built for demanding alpine climbs and thru-hikes where minimal weight is key. The Xero line represents Mountain Equipment's lightest sleeping bags, and the Xero 300, with a trail weight of just 1lb 7oz, fits the niche for colder endeavors with a EN comfort rating of 39-degrees. Implementing all the superior design features that you'd expect of a Mountain Equipment sleeping bag, the Xero 300 has an alpine fit that is snug enough for excellent thermal efficiency but has some extra room in the shoulders for increased comfort. EXL technology, which in short is a stretch stitching, makes the bag more thermally efficient with less added weight. The hood is made with seven baffles to limit down migration, while the Solus draft collar limits heat from escaping from the top of the bag. Ground level seams maximize insulation along the sides, and slanted box wall baffle construction only increases the stability of the down. The lightweight Helium 30 fabric is extremely lightweight and treated with a DWR coating to resist moisture. This fabric combined with the high-quality 850-fill goose down makes the bag exceptionally light and highly compressible. The bag comes with a roll-top, waterproof, compression sack along with a mesh storage bag.


If you're looking to travel light and fast in difficult or remote terrain, then the Mountain Equipment Xero 300 sleeping bag is for you. It's stuffed with the highest-quality 850-fill goose down. Warm, light and compressible, this top-quality sleeping bag features 850-fill-power goose down for a great warmth-to-weight ratio; down is sourced from small farms in Ukraine. He30 outer shell material and hood lining is lightweight and very breathable; soft lining fabric is lightweight, breathable and downproof. Slanted box wall baffle construction keeps down from shifting so you won't feel any cold spots in the middle of the night. 7 baffles in the hood provide excellent down control without adding cumbersome weight. Features a single anti-snag, down-filled draft tube behind the zipper and a neck collar to keep warm air from escaping. 4-baffle foot piece is constructed to minimize down compression and shifting so your feet stay toasty warm on cold nights. Alpine fit has a semi-tapered profile at the shoulders and a tapered lower leg section to keep weight to a minimum. Elastic stitching in the lining of the bag adds nominal weight but effectively minimizes dead airspace around the body for great comfort. Ground-level side seams allow the top layer of the sleeping bag to wrap fully around your body. The Mountain Equipment Xero 300 sleeping bag comes with a roll-top waterproof compression sack and a mesh storage sack.


Mountain Equipment designed the Xero 300 +23 Down Sleeping Bag for the most dedicated minimalist users like fast-moving alpinists and big wall climbers who put performance before maximum comfort. Ground level seams and re-profiled down distribution deliver improved thermal efficiency and cut weight and bulk. Elasticized stitching, the heart of EXL technology, further improves loft and comfort while 850-fill down traps precious body heat. The He30 outer shell is exceptionally lightweight and highly breathable.
