Mountain Equipment Xeros Sleeping Bag (-14°C/7°F)

Mountain Equipment's Xeros Sleeping Bag is an ultra-light winter bag with a water-resistant shell, purpose built for those pushing the envelope of super-alpine climbing on hard, multi-day routes. Part of the Extreme Alpine sleeping bag range, it is designed for hard multi-day alpine expedition use where protection is essential, but every gram counts.

With 605 g of exceptionally high-quality minimum 800-fill power goose down and an extremely breathable and water-resistant Drilite Loft 10D outer fabric, the Xeros thrives in the most challenging alpine environments and can easily cope with snow melt and condensation. For added protection, the Drilite Loft fabric extends into the bag's hood, around the collar, and in the foot box, all areas prone to dampness.

Trapezoid baffles optimally balance weight and pack size throughout the bag against warmth and down control. A complex seven-baffle system concentrates down in the hood and collar for optimum warmth and protection over long-term use. A six-baffle system focuses warmth around your feet in the anatomically shaped foot box. A full-length Gemini zip baffle reduces heat loss in this vulnerable area, and the low-profile magnetic Lode Lock closure and collar drawcords are easy to use in the dark or difficult conditions.

With a Good Night's Sleep Temperature of -14°C and weighing just 1010 g, the Xeros is an extremely warm bag for its weight. This rating, determined through lab work, countless field trials, and exhaustive expedition testing, indicates the minimum temperature at which an experienced user will be comfortable in this bag in real-life situations.
