Mountain Equipment Firefly

The Mountain Equipment Xeros is the lightest weight bag in the Extreme Alpine Range. Expedition bags in all but for the critical weight. The very best 800 fill power down and superb engineering combine to give high quality/lightweight bag for high mountain use. The Xeros is the ideal partner for fast and light alpine winter mountaineering/climbing.

The Drilite Loft Xero outer provides an essential barrier to the elements yet its still super lightweight, breathable and highly water resistant. It has a microporous water resistant Drilite coating protecting the Russian Goose Down from snow and rain, ensuring it maintains its loft at all times.

The bag has an Alpine fit 2.0that is slightly more tapered in the upper body/leg areas so it minimises weight and enhances thermal performance. The Xeros features trapezoid baffles throughout the main body which maximise the retention of down in position and overlap to minimise heat loss. Ground level seams with a V-side baffle on the bag - as opposed to traditional side seams - mean that the top sheet wraps right over your body, increasing insulation.

The foot of the bag uses a six baffle trapezium shape to provide a good sized toe box without any dead spots in the insulation. Throughout the main body the lining utilises EXL elasticated stitching on the baffles to hug the bag close to your body, increasing thermal efficiency, loft and comfort. The hood is constructed of seven baffles to provide excellent insulation and has less deformation when contoured around/over the face. For ease of use in extreme conditions, the closure system is single handed. To improve thermal efficiency the collar also has EXL elasticated stitching, used in conjunction with the normal adjustment system it wraps comfortably around the neck.
