Wide Mummy

A more generous cut for added comfort while you sleep, with space to move your legs. These sleeping bags are slightly bulkier and heavier than our mummy taper shape, but allow a more relaxed sleeping position.

This slim-fitting, technical down sleeping bag blends comfort and packability to bring you a sound night’s sleep, whether you’re high on the summit or deep in the backcountry, on foot or two wheels. It has a clever construction designed to maximise the performance of the 650FP European duck down and offer more heat for fewer grams. The L.O.F.T™ baffle technology reduces down migration and helps retain warmth while minimising the amount of insulation required, which in turn slashes weight and pack size. Finished with a protective, windproof Pertex® Quantum fabric, this low-bulk bag is ideal for alpine missions in cold conditions.

Hand-filled in the UK, all our down bags benefit from never having had their down compressed before use, preserving its loft and warmth.

L.O.F.T™ construction uses alternating wide and narrow baffles to achieve great warmth for weight.
Sleep comfortably on your side thanks to the sidewall baffles, which reduce cold spots and ensure you’re not lying on a seam.
Cinch in the hood to seal in the heat, while the synthetic insulated collar sits snugly around your neck.
Tapered mummy shape maximises comfort while minimising pack size.
Two-way zip provides ventilation when you need it, while the insulated zip baffle prevents cold spots when the temperature drops.
Keep valuables and essentials close at hand with a zipped internal stash pocket.
Internal cordlocks positioned below your collar bone for greater side sleeping comfort.
YKK® anti-snag zip insert and anti-snag internal zip guard.
Anatomically shaped foot box allows you to sleep in a relaxed position.
Drawcord stuff sack included.
Zipped storage sack with water-resistant base for home storage.
Hand-filled in Derbyshire UK.
