Editors' Choice 2008 Gold Award: Marmot Ultralight Down Sleeping Bags

Sleep-anywhere evidence that luxury and lightweight can go hand in hand.

Want to see a down bag puff up like a hot-air balloon? Unfurl one of these 850-fill sacks and stand back. Each bag in this line is overstuffed with the highest quality feathers we've seen–light, compressible, and amazingly lofty. And the down is well-distributed throughout–with enough on the bottom to keep your back from chilling if you roll over. The no-skimp approach to down has made these bags a tester favorite since 2001. Add Pertex Quantum shell fabric–which is breathable, wispy, water-resistant, and durable–and simple designs that are comfortable but thermally efficient, and you get standard-setting bags. If you require separate pockets for your iPod, make-up kit, and dental whitening strips, or other doodads like foot vents and pad straps, these elegant sacks are not for you. But what features there are we love: A muff around the face seals well without forcing you to crank down the drawstrings; the footbox is roomy enough for booties and hot-water bottles; and zippers stay zipped without relying on scratchy Velcro. Plus, there's a version for virtually every trip.
