The Ultralight StormLoft™ Down Underquilt will lighten your pack and improve your sleep with its ultralight design and materials! Our goal was to source the lightest weight fabrics (10D ripstop nylon) and insulation (800+FP down) and then craft them into an ultralight designed underquilt.
The ultralight StormLoft™ underquilt will enable you to shed pounds out of your pack helping you go farther, faster and with less fatigue. The long vertical baffles and contoured cuts keep the down locked into place and reduces the weight even further!
The fully integrated suspension system allows you to quickly adjust the quilts height and tightness with one adjustment point. You can then seal out any drafts with the draft baffle and bungee adjustment!
Live Ultralight by going farther and sleeping better with the StormLoft™ Ultralight underquilt!

Your Stormloft Down Underquilt is a high performance piece of gear. It needs some extra attention to keep it performing at the highest level.
Please read through the care instructions below to ensure that you care for it properly:
- Always wash your down product completely alone to prevent down migration.
- Never wash your down product in a washing machine that has an agitator.
- If you cannot follow either of these prior instructions you should hand wash your sleeping bag using the detergent and drying process described below.
The Wash & Dry Process
- Use a mild detergent like Dreft (for babies) or Nikwax (for technical gear).
- Choose Low Spin or Delicate wash.
- Choose Cold Wash & Cold Rinse.
- Hang dry until the sleeping bag is completely dry.
- Then loft and redistribute your down insulation in the dryer by running it for 10 minutes on low or no heat with 3 dryer balls.
Long Term Storage
- Do not store down product compressed long term. Long term compression weakens the insulation's ability to loft and therefore insulate.
- We recommend hanging it in your closet or putting it in a pillow case for storage between uses.

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
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.
Thanks for your review! We just wanted to make sure you know that the underquilt comes in a stuff sack, not a compression sack. If you have a dry bag or compression sack, you can get the underquilt down to about half the size of what you see when it's packed in the stuff sack.
