Spike Lake Sleeping Bag: 14F Down

If you're hittin' a hut trip or heading out for some any-season camping that won't drop down too far below freezing, the Big Agnes Spike Lake 14-Degree Sleeping Bag's a good bet for warmth, packability, and comfort. Boasting more 600-fill down than a flock of Mergansers, it has the high loft and packability that mountaineers, alpinists, and long-range hikers love, with a water-repellent DownTek treatment (and water-repellent nylon ripstop fabric) that'll help you stay warm even if your bag is exposed to moisture.

The down's kept in place by the Spike Lake's Insotect Flow construction, which uses "gates" to prevent the down from working its way down the bag and leaving cold spots behind, and forgoes Big Agnes' classic integrated pad sleeve in favor of full down coverage for increased warmth. Along with extra warmth, the mummy shape cuts down on weight, letting the Spike Lake check in at right around 2.5 pounds without having to sacrifice key features like the no-draft zipper and collar or the contoured, drawcord hood. And if you have a left-zip and right-zip bag, you can mate them together to make an extra-large, extra-warm two-person cuddle-cave.
