Overview
Not a roomy rectangular camp bag, the Phantom is a close-cut down mummy built for alpine routes and light backpacking. Goose down lofts inside a recycled ripstop shell, while a draft collar, face gasket and contoured footbox seal warm air in.
Warmth for its packed size is why to carry it, since high-fill down compresses small and rebounds quickly. Down loses loft when soaked, so condensation in a tight tent or snow cave calls for care.
Who it's for
Alpine missions, ski tours and light backpacking trips match this bag, where packed volume and warmth both count. Car campers wanting a wide bag, or sleepers heading well below freezing, should look elsewhere.
Pros and cons
- High-fill goose down compresses small
- Recycled ripstop shell saves weight
- Draft collar blocks heat loss
- Down-filled face gasket seals the hood
- Mummy cut limits room to move
- Thin shell needs care on rough ground
- Listed weight figure looks unreliable
- Left zip only in this version
Performance notes
Warmth comes from how evenly the down lofts, and the chambered hood and contoured footbox spread fill where heat escapes fastest. The close mummy shape reduces the air volume your body has to heat, while the collar and face gasket stop warm air pumping out when you move.

Frequently asked questions
Is the Phantom 30F a two person sleeping bag?
The specs list a 2 person occupancy, but the bag is a mummy cut in a regular size with a left zip for sleepers up to 6 feet. Treat it as a single sleeper bag.
How does the Phantom 30F handle damp conditions?
The description says the 10-denier recycled shell gives a barrier against moisture and wear. The fill is down, which loses loft when soaked, so keep it dry in condensation-prone tents.
What does the listed 8 pound weight mean for the Phantom 30F?
The specs show 8 pounds, which conflicts with the ultralight description. Confirm the actual weight with Mountain Hardwear before buying.
