When is a mummy-style bag also constricting? I’ve made use of ultralight, 3-season bags that felt a small also coffin-like. But in winter—or wintry situations, such as you encounter when mountaineering in spring and summer—there are extra sensible factors to use a bag with further space, and you get it with the Storm King . Beyond its dimensions, the Storm King’s water-resistant down feathers, pretty distinctive “system” design and style that calls for sliding an air mattress into a sleeve on the bag’s bottom side, and its comparatively inexpensive cost for this category of bags merits a close appear.

My 15-year-old son and I swapped off making use of this bag and a different -degree model for 3 nights camping on snow in temperatures as low as the teens Fahrenheit on a 4-day climb of the Mountaineers Route on California’s 14,505-foot Mount Whitney in mid-April and for 3 mid-February nights skiing and snow camping in Idaho’s Boise Mountains, with lows ranging from just under freezing to the mid-30s. Although I discovered it also warm for temps above freezing, my 13-year-old daughter, who gets cold really very easily, loved this bag’s warmth on a backpacking and auto camping trip in March in southeastern Utah, with lows from the 40s to under freezing.

The semi-rectangular Storm King is noticeably roomier than numerous backcountry bags: the standard measures 70x65x53 inches. I could very easily roll about, get dressed inside the bag (a major plus in sub-freezing temps), and sleep in extra organic and comfy positions—closer to the knowledge of sleeping in my personal bed (except for the snow). I stuffed my pants and base layer major deep into the vaulted foot box (which has extra space for feet than most backcountry bags), each to add a small insulation for my tootsies and so my garments would be warm in the morning. And but the bag’s space does not compromise warmth by getting also substantially true estate for a modest individual to heat up: My son and daughter, each slightly extra than 5 feet tall and 100 pounds on these trips, stayed warm on nights effectively under freezing.

Inside the bag is 24.five ounces (26.five ounces in the extended bag) of water-repellant, 650-fill Downtek down feathers, which resist absorbing water substantially greater than common down and dry more rapidly as soon as wet. Although the 650-fill top quality tends to make this bag a small bulkier and heavier than bags with larger fill energy down, it is also significantly significantly less expensive—about 3-quarters to half the cost of numerous higher-top quality -degree bags—and the standard bag nonetheless compresses to a manageable 8×9 inches.

Like numerous Huge Agnes bags, the Storm King lacks insulation on the bottom it is all on major, exactly where it is most functional (rather than obtaining flattened underneath you), and a mattress slides into a sleeve on the bag’s bottom to insulate you from the snow or frozen ground. As a side sleeper, I haven’t generally liked this technique mainly because the hood does not have a tendency to turn with your head. But the Storm King’s redesigned hood now moves no cost of the pad sleeve: Although it does not turn a complete 90 degrees with my head, it is an improvement more than the preceding design and style, and the bag’s draft collar covers whichever ear is facing up. Plus, there’s an even stronger argument for this system—integrating the pad with the bag—in winter, when your bag sliding off your pad will make you cold quick and could wake you repeatedly.

The fat hood, collar, and draft tube along the non-snagging zipper maintain warm air in and cold air out. The shell fabric is not waterproof, but is treated to repel moisture, which protects against moderate condensation inside a tent. Stretch fabric on the sides of the pad sleeve accommodates air mats in a variety of thicknesses. Lastly, I like the stretch-fabric pillow pocket beneath the hood.

No matter whether you are camping in winter situations, just choose a extra spacious bag, or like the Huge Agnes technique of incorporating the air mattress into the bag, the Storm King sleeping bag delivers quite a few factors to suggest it.
