AKMAX Down Mummy Sleeping Bag -13°F Cold Weather Camping Backpacking

- Goose down fill named
- -13 to 23 degrees F range
- 2.37 kg (5.2 lb)
Our take
The only bag in this list that names goose down, in a warm mummy cut.
Why it made the shortlist
The AKMAX is the one bag here whose listing names goose down as the fill. It is a mummy-shaped bag with a water-resistant nylon shell and a printed temperature range of -13 to 23 degrees F.
It lists a weight of 2.37 kg (5.2 lb), and the snug mummy cut wastes less air than the two OMVMO rectangular bags. That tighter shape is what lets it claim the coldest range of the three.
It suits winter campers and backpackers who want goose down specifically and are happy to trade roominess for warmth. The shell is rated water-resistant for damp mornings.
What works
- Listing names goose down as the fill
- Printed range reaches -13 degrees F
- Mummy cut holds heat close
- Water-resistant nylon shell
Watch out for
- Heavier than a trail-weight down bag
- Fill power is not printed
- The catch
- The listing prints a wide range but no fill power, so judge warmth by the lower end of the range only.
