Zipperless bag. Simple, light and no nonsense. If you need this you will know.

High quality 900 fill applied in a generous quantity, cord at the top, light fabrics, no inward taper until hips. Pro tip: down can be shuffled from topside to underside, or vice versa.

Perfect inside a synthetic over-bag for gnar conditions.

Concerned about getting in and out of a zipperless bag, and hot weather venting? Look elsewhere.

Roomy or mummy, selectable in menu.

The roomy cut maintains shoulder width to hip level, giving more space to move than found in an average sleeping bag. This may be appreciated in a zipperless design, but leaves air space to warm up

Some folks might prefer the rapidly tapering mummy cut for a more efficient shape

Sastrugi; snow eroded by wind into ridges. A skiers nightmare.
