Phantom Sleeping Bag: 30F Down

What Our Gearhead® Experts Are Saying:

"The Phantom 30F is one of those bags you bring when weight matters, but you still want dependable warmth. It packs down incredibly small, lofts quickly, and the mummy cut seals in heat well on cool alpine nights. I like it for long backpacking trips and hut traverses where space in the pack is at a premium."

After a long day of climbing, hiking, or pushing deeper into the range, the Phantom 30F Sleeping Bag becomes the most welcome piece of gear in our pack. Designed for alpine missions and lightweight backpacking, it delivers reliable warmth without weighing down the miles ahead.

High-lofting 800-fill RDS-certified goose down traps heat efficiently while maintaining exceptional compressibility for ultralight travel. The 10-denier recycled shell keeps weight to a minimum while providing a surprisingly durable barrier against moisture and wear, borrowing the same lightweight fabric used in Mountain Hardwear’s Ghost Whisperer series.

A performance mummy shape maximizes warmth-to-weight efficiency, while a contoured footbox and draft collar help seal in heat during chilly mountain nights. The four-chamber hood maintains even loft around the head, and the down-filled face gasket blocks cold drafts when temperatures drop toward freezing.

With a highly packable design and thoughtful alpine features, the Phantom 30F is built for climbers, backpackers, and ski tourers who count every ounce but still expect dependable warmth when the day’s adventure finally comes to rest.
