StormLoft™ 0°-30°F Down UnderQuilt

This is a must have for sleeping in a hammock. I was sceptical but after spending a few cold nights in the mountains this summer I got this for our backpacking trip in the high uintah's. I was amazed at the warmth that came from this under quilt. Ease of setup and paiing nicely with OV quilt, hammock, and net make this worth the weight for a great night sleep.

This is my second zero degree under quilt. I love my first one so much, I bought a second one. Now when I share winter hammock camping with my friends, they can be sleeping in the best setup.

Looks super confey

I have the stormloft top quilt and was happy with it so thought I’d give the underquilt a try. This quilt is a miss for me. The way the suspension connects to the body causes a pull on the outer fabric that compresses the loft in the shoulder area. I have been able to deal with this somewhat by schrunching the quilt lengthwise while hung, but this is not an ideal solution. I’ll be replacing it with a different UQ.

Tested for the first time at around 35 degrees this weekend. I had to take layers off due to being on the warm side - good problem to have as opposed to the cold. It was narrower than I thought it would be but was just the right amount for me (5'11" 215 lbs). It was really compressed on arrival, but I followed the included instructions and it lofted up really well. Overall it works great!

Love it definitely worth the money!

2 budys of mine bought this under quilt for backpacking trips after freezing my ass off and looking around n hearing how warm they were during cold Midwest 20degree nights I instantly knew on arrival that i made the right choice! Used it as a blanket to “break er in” 1st night on the couch n as we know you can’t go wrong with high quality down winter gear!

Love it, fast shipping, great company.

My first experience hammock camping in the winter. New Hampshire has cold nights and I wanted to make it was a good experience. I was warm and cozy. I purchased the under quilt and top quilt. Light weight and built right!

This underquilt is super light and very warm. I used it in 23 degree weather and I was plenty warm. Great product.

It appears as if it couldn't be warm enough, but I just got it, so...

I purchased 30 and 0 degree underquilts from Outdoor Vitals. The quality is ok. The temp ratings are fine for a warm sleeper. They don't seem to have any overstuffing so watch out for down migration. The line locks are garbage. You MUST tie knots in your suspension to keep the line locks from loosening. I found these quilts impossible for wide hammocks. They are very narrow with a simplistic suspension and probably work best with narrow hammocks. If you have a wide hammock, I would look for underquilts with better suspension so you can get the higher angle lay with less frustration. After several cold and restless nights I was ready to unload these quilts but then I decided to try them on a bridge hammock. The narrow tapered shape of these quilts actually worked great with a bridge hammock. So, if you have a narrow hammock or a bridge hammock and you're looking for a more budget friendly underquilt, the these underquilts might be a good option.

I just received this under quilt along with the 0 degree top quilt
I’ve only had an opportunity to make a short hike early in the morning with a temperature of 30 Fahrenheit
I use a Hennessy hammock and
the set up was easy and self explanatory
At 30 degrees with the top quilt I was toasty within a couple of minutes
Granted I only stayed in it for about an hour while reading a book, but I’m very happy
I’ll be spending 5 nights on the AT in North Carolina this Christmas Holiday for the real test
But I don’t think I’ll be changing my opinion
Thank you

Tayson noted in a video how the people assembling the underquilt put the sbiner in the wrong place. They also printed the company logo upside down on my 15° quilt. That brings a concern to mind as to what else they may have messed up. Did they not put as much down in as they should so my 15° underquilt is actually a 30°? I mean the stitching is fine, not loose threads, no tears or burrs, but still the logo upside down? That's quality control 101. I bought this for shoulder season use and I am now wondering if it can do the job because such simple things were done wrong.

I purchased this 30 degree Stormloft Underquilt for use with my Kammock Manits UL. This is my first experience with an underquilt, so I understand that there will be a fairly steep learning curve to get it set up right. Out of the box, the first thing I noticed was that the quilt had a very strong odor that was quite unpleasant. After a few days of hanging it out in the open, it seems to have lessened. Second, I noticed that the materials were different than my OV Topquilt (30 degree and purchased at the same time). While this isn't a big deal, I just find it odd that the products have different materials and colors when they appear to be the same on the website and are described similarly. While I haven't used it in the field yet, I have set it up and spent a lot of time adjusting it with my hammock in my yard. One thing that is frustrating right off the bat is that the cord lock toggles don't clamp down hard enough on the shock cords at either end of the quilt. They essentially slide freely over the shock cord with very little "bite". We'll see how well this functions when using it out in the wild. I did make an adjustment to stabilize the quilt under my hammock by attaching small clips from the open shock cord on the sides of the quilt to the loops on my hammock. This helps to keep the quilt from curling under the hammock when I lay diagonally. I hope that when I use this this fall, that my initial concerns about the quit are unfounded... stay tuned.

Used the 15 degree stormloft underquilt this last weekend and it was great. Nice size, great loft, and great coverage. Only thing from 5 stars is if it could compact down a little smaller.

After a couple uses, the stitched tab that holds the shock cord adjuster in place ripped. The quilt is no longer held in place allowing the draft collar to gape open. Add a few grams and use stronger materials at this point. I contacted OV and they noted that I would be paying shipping to return a quilt for repairs that was less than a few months old. I just stitched it myself.

When workings correctly, the quilt (30 degree) kept me comfy down to 35F.

I give the bag 3 stars and the return policy 1 star.

The material and stitching is so poor and flimsy that it tore after setting this up once. Where the shock cord connects to the underquilt near the draft collar adjustment is a thin, poorly attached piece of material that is single stitched. It takes less than a few pounds for this to just rip away from the underquilt itself rendering that bag ineffective. The material of this underquilt is so weak and thin it feels like you can rip it in half if you brush your hand against it the wrong way.
For how much you pay for this bag you would think they would at least double-stitch the attachment points.

I own the 15 degree bottom quilt and love it. I use it all year long in all weather. Takes a minute to get used to hanging this up how you want it. Soon it becomes like riding a bike. This under quilt is just like all of the quilts and bags by OV. extremely ultralight, packs down so small, true to temperature ratings, and very affordable. I give this a 10 star rating!

I’m by no means an ultralight backpacker but it fits my needs really well. Love it.

love my 0 degree Stormloft Top quilt. Very warm. Glad I baught it. Worth every penny.

I have the 0F top and bottom quilt for this and they are amazing. I also have the loftek version and after a season of that was ready to upgrade to the full down and save some weight in my pack. Best decision ever. I now have 2 full sets of top and bottom quilts so can introduce new people to hammock camping. Thanks guys! BTW- the recent Dan Becker YouTube video with you guys was awesome. Can't wait to check out some of the new gear!

I bought this quilt because it got good reviews, and I didn’t want to spend the money on a higher priced one from a competitor. I have been more than pleased! It packs down nicely and has kept me very warm even on a pretty cold night — not quite down to the 15* rating but probably 25. My only complaint is that the shock cord doesn’t like to hold that well in the cord locks, and I’ve had to tie it. It seems like it’s maybe a little too tight for my hammock length even though it’s within the range of what it was intended for. Still, that’s easily fixed, and I’ve managed to stay cozy.

I had a bad experience with a cheap underquilt and decided to get the Stormloft 15 degree to avoid CBS (cold bum syndrome). Took it for the first time to the Uintah’s. All the way up the mirror lake highway the temperature continued to drop the higher we climbed. When we got out at the trailhead it was raining and at a balmy 60 degrees. Got to the lake right at dark, 1000ft higher in elevation and the temp was in the 50’s. laying in the hammock I felt cold right away. Thinking I had just wasted a bunch of money I reached over my head to see if I cinched up the baffle and felt it on the outside of the quilt. I realized I had slung the underbuilt upside-down which squished the down flat against my back. Think straightening out a banana and you’ll get the picture…DOOH! After flipping my quilt to right-side up and climbing back in I started to warm up right away. I don’t know how cold it got, but I woke at 3am, hot. That just does not happen with an inferior product. Money well spent!!
