Why We Like The Mountain Hardwear Phantom 0F Down Sleeping Bag

The Mountain Hardwear Phantom 0F Down Sleeping Bag packs down small and light while offering big-time warmth for camping in winter conditions. Clocking in just over two-and-a-half pounds, the ultralight mummy bag is designed to fit close to our body to minimize heat loss, with a DWR treatment to ensure the down stays lofty as condensation builds in our tent or portaledge. The contoured footbox gives our feet room to move and ensures our feet stay warm throughout the night, and the draft collar keeps our core warm so we can maximize our rest before the summit push.

Gold Standard for 0F.

Alaska, Himalaya, Andes- you name it. This is your bag. The Phantom 0F is the right size, the right warmth, and the right materials for the job. I use this all over the world and consider it to be the best option on the market for this temperature rating. Comes with an awesome 3 strap compression sack and packs very small. You can easily sleep in this bag with other things inside as well (ex: gloves, water bottles, boot liners). Great product.
