For the past five years, I’ve relied on quilts as my primary sleep system, especially when hammock camping in the Sierra Nevada. They give me the freedom to move naturally, regulate heat, and stay cozy in ways a traditional mummy bag never has. So when I came across the Outdoor Vitals StormLoft™ 15° Quilt (Long) at OMA in Denver earlier this summer, I knew it was time to test it out. After 8 nights on trail and over 70 miles of backpacking—split between the Emigrant Wilderness and Yosemite backcountry over Labor Day weekend—I can honestly say this quilt has exceeded expectations.
Testing in Real Sierra Conditions
This quilt has seen real Sierra miles.
- Emigrant Wilderness: Four nights in the rugged southern Emigrant backcountry, where daily pack-ups and granite scrambles put both durability and packability to the test. Nights dipped into the low 40s, and the quilt’s warmth and roomy cut made it easy to sleep comfortably after long days of lake-hopping.
- Yosemite Backcountry: Over Labor Day weekend, I spent another four nights exploring beyond Tuolumne Meadows. On the coldest night near Nelson Lake, the temperature dropped to 34°F. I lay warm and cozy in my hammock, quilt snugged up to my nose, feet resting comfortably in the footbox while coyotes called from the meadows. It’s nights like these—where the wilderness feels alive around you—that remind me how essential a reliable sleep system really is.
These aren’t controlled conditions—they’re field realities. And the StormLoft handled every one of them.
The Comfort Factor: Puffy, Lofty, and Snug
One of my favorite features of this quilt is how quickly it puffs back to life after coming out of the compression sack. Within minutes it feels like a warm, down-filled cocoon. The wide shoulder region and insulated draft collar create a snug feel against the cheeks—something I appreciated on colder Yosemite nights when I tucked in deep.
I’ve used quilts before without footboxes, and often ended up sleeping in socks to compensate for cold spots when I shifted around. The StormLoft’s sewn footbox eliminates that problem entirely. My feet had a dedicated “home,” no matter how I positioned my legs—tucked, sprawled, or crossed mid-sleep.
Tech Features That Made a Difference
Outdoor Vitals clearly built this quilt with more than just weight savings in mind. A few standouts:
- ExpeDRY™ Down (800FP): Treated with FUZE technology, this down dries faster than traditional DWR-treated down. In Sierra conditions where morning dew or condensation is a given, quick dry time matters.
- Draft-Free Shape: The tapered cut naturally wraps the body. I moved a lot at night but never noticed cold air sneaking in.
- Boxed Baffle Draft Collar: Easy to cinch, seals heat at the shoulders, and feels soft—not restrictive.
- Pad Straps & Buckles: For ground sleeping, the included straps are simple to set up and prevent sliding off the pad. Hammock campers won’t need them, but they add versatility.
- Weight & Packability: At just 1 lb 10 oz (long size), it’s ultralight. Packed into the roll-top dry bag, it slides into the bottom of my pack without hogging space.
Durability on the Trail
Back-to-back days of stuffing gear into a pack is where many ultralight pieces start to show weakness. So far, the StormLoft has held up beautifully. The 10D ripstop nylon shell feels thin but durable, and after over a week of trail use—including granite scrambles, meadow crossings, and brushy off-trail detours—there’s no visible wear. The loft has stayed consistent, which tells me the baffles are holding up well.
Pros & Cons

- Roomy, anatomically shaped footbox even for larger feet
- Quick loft recovery after compression

Sierra Rec Recommendation
For anyone planning multi-night Sierra Nevada backpacking trips, the Outdoor Vitals StormLoft 15° Quilt should be on your radar. It strikes a rare balance: ultralight performance, thoughtful comfort features, and durability that holds up to real backcountry use.
My field tests in both Emigrant Wilderness and Yosemite’s high country proved that this quilt performs when it matters most. Whether you’re stretching out in a hammock listening to coyotes echo through alpine meadows, or crashing hard after a 12-mile granite slog, this quilt delivers the warmth and comfort you need.
Sleeping comfortably in the wilderness is one of the most important parts of any adventure. The StormLoft 15° makes that possible—night after night.
