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.


Traditional Mummy bags deliver value and comfort in a lightweight bag. Budget minded backpackers and dirtbags on the dole will want to get hooked up with the Big Agnes Spike Lake 14 down bag which is insulated with high quality down and constructed with Insotect Flow patented technology. If you're in search of a lower priced mummy shaped bag constructed with top notch, lightweight materials, these will help you travel fast and light.

The Big Agnes Spike Lake 14 is a traditionally insulated bag designed without the integrated pad sleeve found on other Big Agnes System bags. Couple that with the Insotect Flow baffle construction and you have one of the lighter, warmer bags in it's class. Take the Spike Lake out all year long, it's versatility is remarkable.Insotect Flow is a flow-optimized insulation system that delivers uniform heat distribution and natural body contouring through its revolutionary baffle design. Flow Construction eliminates lateral and vertical down shifting by using vertical chambers with Flow Gates to regulate fill positioning and density. Strategically placed Flow Gates minimize vertical down shifting while vertical chambers minimize lateral shifting. With continuous vertical Flow chambers in place of traditional side seams, Flow bags eliminate potential cold spots which can occur with side seams. Vertical baffles now flow with your body for more rapid and uniform body heat distribution.
