MOUNTAIN HARDWEAR

Phantom 45D • $205 • WEIGHT: 18 ounces

The Phantom 45D is a fully featured lightweight bag, the only model with a down baffle in the hood and neck, and a down-filled zipper draft tube. Its half-length zipper opens from the top and bottom. These features make it the Cadillac of sleeping bags, but nudge its weight to just over a pound.

The Phantom 45D is conservatively rated to 45 degrees. Two testers (wearing light layers) used the model comfortably in a snow cave, while others used it during a blizzard on Mount Rainier. Despite the bag’s durable water-repellent (DWR) treatment, in heavy dew you should use a bivy sack or tent. The Phantom 45D is a medium mummy, wide enough for light layering, but not so wide as to create heat-robbing air pockets. This bag is a good choice for people who want the features of a heavier, more expensive bag in a lightweight, inexpensive model.

PROS Has the best hood. One of the warmer sleeping bags. Fully featured. Budget price.

CONS Heaviest bag tested.

RECOMMENDED USE Alpine bivies and camping from 35 to 60 degrees. With layers you can take it down to freezing.
