Gear Guide 2009: Mountain Hardwear Phantom 15 Sleeping Bag Review

This ultralight bag will stuff-to-fit anywhere you've got room.

Durable Ultralight

Our staff ounce-counters swear by this proven bag, which is eerily light for the warmth, yet has held up on dozens of trips without ultralight TLC. The 15-denier nylon shell is sturdier than it looks, and durable craftsmanship prevails throughout.

The 800-fill down compresses so small you could slip this bag into a pack's water-bottle pocket. All testers praised the hood, which closes snugly around the face to seal out drafts, and the mummy cut fits close without constricting–one cold sleeper stayed warm in 20°F temps high in Rocky Mountain National Park. "This is a Goldilocks bag–just right," he said. Even the stuffsack fits perfectly–and it should, considering the price. $400; 1 lb. 15 oz.; 15°F
