In this article, we’re going to review the best hammock underquilts on the market for 2026 to help you choose the right under quilt.
Whatever purpose you’re mounting a hammock for, you certainly can do with more cushion, usually obtained through a hammock sleeping pad or under quilts.
When you need to set up a place to sleep as a bikepacker on the road or a camper, however, you need much more than a cushion: you also need insulation from the cold and protection from moisture.
This is why you need a hammock mattress pad and/or an underquilt to keep you comfy on your hammock-camping nights.
To purchase the best hammock pad and underquilts, read our passionately curated guide.
What are Underquilts? Are they better than sleeping pads for hammocks?
Hammock underquilts are sorts of quilts designed to hang underneath your hammock to prevent heat loss. They look like sleeping bags and are filled with down or synthetic insulation. They hug your hammock tightly with adjustable straps and are a great help in keeping a hammock camper warm on a chilly night.
While a sleeping pad can also help reduce heat loss by creating an insulated air space beneath you, underquilts are explicitly designed for hammock camping and fit snugly to your hammock’s shape.
If you’re planning to camp in low temperatures, using both an underquilt and a sleeping pad might be advisable.

The 5 Best Hammock Underquilts for All Budgets
1. ENO Vulcan
The Vulcan UnderQuilt keeps you warm and snug in your hammock while protecting you from inclement weather.
To protect you from the elements, it features a ripstop nylon shell with a water-repellent finish.
Two layers of Primaloft insulation, with an offset quilted construction, provide the best hammock insulation.
The manufacturer’s updated ENO Vulcan features a fully adjustable shock-cord suspension system that’s easy to set up, works with any standard hammock, and adapts to any sleeping position.
The Vulcan UnderQuilt fits users up to 6’2” and includes a large mesh storage bag.
2. OneTigris Hammock Underquilt
OneTigiris Hammock Underquilt offers a unique experience you won’t get enough of.
The winter underquilt is ideal for temperatures from 23°F to 41°F, and the 3-season underquilt is perfect for temperatures from 40°F to 68°F.
It is shaped to fit a hanging hammock made of materials that keep you warmly cocooned and shield you from the wind.
It also shrinks to a small size, fits in any rucksack, and weighs very little. Keep the cold off your back with this highly serviceable piece of gear.

3. Outdoor Vitals Aerie
How do you sleep comfortably without packing a car full of gear? The answer is simple: Outdoor Vitals Aerie 5-in-1!Â
The manufacturers designed the Aerie 5-in-1 Down Sleeping Bag in the rugged backcountry of Southern Utah. They field-tested it at 12,000+ foot peaks, all the way to desert floors and slot canyons.
From there, they sourced IDFL-certified and RDS-sourced down, YKK zippers, and quality milled ripstop fabrics to put together components for premium performance.
Last, they flew around the world and met with manufacturers to ensure their gear was made in ethical, high-quality manufacturing facilities! The result is an ultralight down sleeping bag that will cut weight from your pack, cost only a few bucks, and keep you warm!
4. Snugpak Hammock Cocoon
The Snugpak Hammock Cocoon does its job of being a heat-repellent underquilt. Although it restricts diagonal lay slightly, it doesn’t disappoint because that’s expected.
The bag will be better with a suspension point attached to a ridgeline to keep the head end off the face, and I have emailed Snugpak to inform them.
It works fine at 14°F/0°C with light wear and socks and no inner bag or pad. I have yet to test it in colder conditions, but you can easily supplement it with extra clothes, an inner sleeping bag, etc.Â
5. ENO Eagles
There’s an updated version of the Blaze Underquilt available from the manufacturer (ENO) right now. They enhanced the old one with DownTek water repellent down.
With the shock cord suspension rails, you will easily set it up, and the differentially cut design will keep you warm all night.
When unfolded, it spreads out to a dimension of (L x W) 6 6″ x 4′. It weighs 24 ounces. You can pack it into a stuff sack measuring 14’’ by 7’’ when you’re done using this underquilt.Â
Besides the regular stuff sack, ENO included a larger storage sack to store your ENO Eagles when you’re not using them for extended periods.
ENO recommends using the storage sack rather than the stuff sack because it extends the life of your underquilt.
Air mattress or under quilt for hammock camping?
| Underquilt pros | Sleeping pad pros |
| Won’t interfere with your natural hammock sleeping position | Though the hammock fit can be less than ideal, you can use it in both a tent and a hammock. |
| Models with high-loft fills provide superior warmth | For a better fit, get models designed for use in hammocks |
| You can deflate air pads slightly in a hammock for a better fit (deflate too low, and you’ll have cold spots; deflate too high, and your setup can get a little tippy) |
Frequently Asked Questions about Hammock Underquilts
Hammock sleeping pad vs. underquilt, which one should I go for?
By creating an insulated air space underneath you, a sleeping pad solves the heat-loss problem on the ground. Underquilts, on the other hand, are specifically designed to fit specific hammock models, even though a pad can perform the same function in a hammock. You will also discover adjustable underquilts that can accommodate a wide range of hammocks.
How to set up an underquilt?
Each underquilt comes with instructions, so that’s your first source for a fit recommendation. The following universal tips, however, will help you create the warmest possible setup for your underquilt:
1. Lay the quilt inside the hammock to start to prevent it from getting wet or dirty on the ground, then attach the ends and remove enough slack so that it suspends at the desired height when you slide it out of and under the hammock.
2. With you in the hammock, minimize the air space between the hammock and the top of the quilt. Snug up the adjustments to keep the quilt close but not too close so your body won’t compress it.
3. To prevent air from flowing through, snug each end tightly.
4. To prevent airflow gaps from forming there, secure any attachments along the sides.
