Why We Like The Bantamweight Sleeping Bag
When we need a warm but extremely packable bag for a shoulder season backpacking mission we opt for the Marmot Bantamweight Sleeping Bag. This mummy-style bag features a short chest zip and curved baffles to ensure we are well insulated and warm when sleeping and not weighed down when on the move.
Details
- Lightweight sleeping bag built for through hikes and backpacking
- Down insulation traps heat while remaining lightweight and packable
- Short chest zip limits heat loss while minimizing weight
- Curved baffles prevent down from slipping and condensing
- Mummy style with a hood traps heat that escaped from your head

Marmot Bantamweight 15° bag
Incredibly warm and super lightweight! Great bag! Not a huge fan of the partial front zip. (Kinda hard to get into and out of)

This bag is assume.
[This review was collected as part of a promotion.] I cannot wait to take this bag on the Arizona Trail this year. 900 fill goose down. I'm sorry but I am not a "quilt guy". I enjoy the mummy shape. It is my favorite bag.

Cozy
Cozy and warm. No room if you want to bring in your boot liners. Pretty tight for a big guy (across the shoulders) and similarly tough to get into the bag with the short zipper. Beautiful bag and super compressible.

Premium Bag for Wide Range of Activities
The Bantamweight bag fits a wide range of temperatures and conditions. Its a very lightweight and compact performance sleeping bag. Ive used this for multi-day alpine routes and camping in a tent. Temperatures ranged from 0 degrees to 40 degrees F. I use this bag a lot for travel to save space and weight. For very low temperatures (while climbing a big mountain for instance), I wear a jacket while sleeping. Attached is a gear testing video of the Bantamweight with an adjustable footbox. Though not included in the production model, that particular feature is included in other marmot bags.

Is the 7D nylon shell treated to be water resistant?

Is it safe to compress to a size of Nalgene bottle? It looks like lots of tension on compression bag which can be damage faster. I am comparing with Pajak Radical 4Z which can be compressed safely to small size.
