Next order window: JUNE 8 - NOON MT SOLD OUT
The SeasonFour is a winter oriented hooded, but still zipper-less top entry Sastrugi based bag
Wide open hood to facilitate entry, with 5" draft collar controlled by an internal and external draw cord
2.75" loft for the 18°F, 3.25" loft for the 10°F
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
18°F size 74" - 59" - 40" in 10d fabrics and no overfill: 20.3 oz down with a 29.0 oz total weight
10°F size 74" - 59" - 40" in 10d fabrics and no overfill: 26.5 oz down with a 35.5 oz total weight
Top entry, zipper-less bag built to last
