Ultralight Phantom 0F Down Sleeping Bag delivers serious warmth for cold alpine nights

What Our Gearhead® Experts Are Saying:


"I bring this bag when weight and warmth are equally critical. It packs down impressively small for a 0-degree bag and still delivers dependable warmth on frigid nights. The mummy fit and draft collar do a great job sealing in heat, making it a solid choice for winter camping and high-alpine objectives."


When cold nights stand between us and a big summit day, we crawl into the Phantom 0F Down Sleeping Bag from Mountain Hardwear knowing we’ll get the rest we need. Built for winter conditions and alpine environments, this ultralight bag delivers serious warmth without weighing down our pack, letting us move efficiently through demanding terrain.


High-loft down insulation traps heat efficiently while compressing small for fast-and-light missions, and a close-fitting mummy shape minimizes dead space to reduce heat loss. Thoughtful features like a contoured footbox and draft collar keep warmth consistent from head to toe, even as temperatures dip deep overnight. Designed to perform in cold, exposed environments, this sleeping bag is a trusted companion for winter camps, portaledges, and early-morning alpine starts.
