| Pick | Price band | Weight | Best for | Limitation |
|---|---|---|---|---|
 | Upper mid | Moderate | People who hate mummy coffins | Larger pack size than a slim mummy |
 | Mid to upper | Light for a 15°F bag | Most backpackers who want a returnable down bag | A slim mummy, and the rating is a limit |
 | High | Low for the warmth | Cold sleepers and shoulder-season ground | Overkill, and warm, on hot summer nights |
 | Mid | Light | A camp puffy you can try on | Down collapses when wet |

The picks
Best for active sleepers
NEMO Disco 15
The Disco is for people who wake up because a traditional mummy binds them. The spoon shape is still a bag, not a blanket, so you keep the hood and you still need a pad. Thermo gills help on the nights that are warmer than the rating. You pay in packed volume.
Who should buy it. Active sleepers who have already returned one slim mummy.
Pros
- Knee and shoulder room
- Solid warmth class
- Useful vents
Cons
- Not the smallest pack size
- Premium price

Best default down bag
REI Co-op Magma 15
The Magma 15 is the practical down mummy: light enough for a weekend, warm enough for a surprise frost, and sold where you can lie in it and return it. Treat 15°F as a limit unless the brand states a comfort rating. Cold sleepers should buy warmer than the forecast, or pair this bag with a high-R pad such as the XTherm, not with a three-season XLite alone. The cut is a slim mummy. If you thrash or sleep with your knees out, a roomier bag is the fix, not a different fill power in the same shape. A quilt such as the Enlightened Equipment Revelation wins only if you sleep warm and will strap it to the pad. The bag is not the pad. Down also fails when it is soaked, so a wet trip is a different choice.
Who should buy it. Backpackers building a first real sleep system for spring through fall.
Pros
- Usable warmth for the weight
- Easy to try on
- Hood that cinches
Cons
- Slim cut
- Not expedition fill
Not sold on Amazon US. The closest match, NEMO Disco 15, is #1 on this list.
Best cold-weather air pad
Therm-a-Rest NeoAir XTherm
The XTherm is the pad you add when camps drop near freezing and you sleep cold. It is not required for July in the woods. You can vent a bag. You cannot invent ground insulation you left at home. Still carry a patch kit. Warmth does not make it immortal.
Who should buy it. Cold sleepers extending the season without a full winter kit.
Pros
- High R-value
- Still packable
- Warm sleeper insurance
Cons
- Price
- Can sleep hot in summer

Best default camp puffy
REI Co-op Magma Hooded Down
Put this on when you stop. If you hike in it, you will soak the down from the inside, which is worse than rain. The hood is the feature that makes camp tolerable in wind. Return it if the shoulders bind over a fleece.
Who should buy it. Three-season backpackers who need a static layer.
Pros
- Hood
- Packs small
- Returnable
Cons
- Useless when soaked
- Too warm to hike in
Not sold on Amazon US.
Closest on Amazon: Mountain Hardwear Ghost Whisperer Hoody. An 800-fill ultralight down hoody that does the same job as the Magma Hooded Down. The price on the listing varies by color.

If you only buy one
Spend the money on the pad and a lower temperature rating before you spend it on a lighter shell.
FAQ
Will a liner fix a cold bag?
It adds a little. It does not turn a summer bag into a frost bag.
Should I wear clothes in the bag?
Dry layers, yes. Damp hiking clothes, no.
