While you don’t technically need an underquilt to camp in a hammock, there will always be times where you really wish you had one.
When the weather is less than perfect, you need that underquilt to keep you safe at night.
It’s not like shopping for the same kind of bedding you’d use in your room – selecting the best hammock underquilt is a totally different process.
We lose around 65% of body heat through radiation when sleeping, and since a hammock is colder than a tent, this makes it extremely important to make sure that you’re insulating yourself against heat loss from all directions, not just on top.
As most sleeping bags don’t provide a huge amount of insulation under the body once compressed (this is usually where sleeping mats or pads would play their part), using a hammock underquilt is a sure way to ensure that you stay warm and cozy all night.

So, What is an Underquilt?
An underquilt is essentially a quilt of similar material to your standard sleeping bag that gets attached to the outside of the hammock bottom, ensuring that it insulates you without being compressed by your bodyweight.
In terms of what you’d usually take for a backpacking trip with a tent set up, think of the underquilt as the hammock equivalent of the sleeping mat.
So, why can’t I just use a sleeping mat?
Hammock Underquilt vs. Sleeping Mat or Pad
The short answer is, you can.
But there are pros and cons to the different options.
Inflatable sleeping mats or closed cell foam pads can work well in a hammock. It just comes down to personal choice and what you can afford.
While underquilts are usually more expensive and a little trickier to set up (until you get used to them), they may be warmer, pack up smaller and lighter, be easier to carry and be more comfortable.
Mats or pads may end up being less comfortable as they won’t come up around your sides, they’ll result in more moisture build up (you’ll wake up a little more damp), you may roll off them in the night, and hammocks that gather at the end may result in your mat or pad bunching or buckling.
An underquilt solves all of these problems by keeping your sides insulated, being breathable, preventing moisture build-up, and being impossible to roll off!
It’s important to note that you shouldn’t use a conventional sleeping bag in a hammock, as the sides of the hammock will compress the sleeping bag and make it fairly useless in keeping you warm.
The best combination for hammock sleeping is an underquilt, that goes underneath the hammock and a little up the sides, and an overquilt, that goes on top of you.
Underquilts vs. Sleeping Bags
Note, this doesn’t mean using the sleeping bag in its conventional way (sleeping inside it), as mentioned above, once the bottom of the sleeping becomes compressed, it will be doing little to keep you warm.
This method actually involves zipping the sleeping bag around the hammock with you inside.
If you don’t want to use an underquilt, or if you need something you can use for both hammock camping and tent camping, a large sleeping bag might do the trick.
Wrapping a sleeping bag around your hammock and zipping yourself in will protect you by putting you in a large cocoon.
This isn’t always convenient – if it’s hot outside, it may be uncomfortable to use a sleeping bag as an underquilt. It’s also a little more inconvenient to get in and out.
Despite the fact that you’re a bit trapped, you’re definitely going to be warm. The bags help preserve body heat, as long as you keep yourself sealed in.
Things to Keep in Mind when Picking the Perfect Hammock Underquilt
If you ever plan to camp in winter, you really need to get a four-season underquilt. Four seasons means the underquilt is designed to work in winter.
It will have better padding on the inside, and the outside will be water resistant to prevent soaking snow.
Three season hammocks are fine for campers who don’t often venture out into the cold.
They’re also great for hammock campers who live in climates that don’t see especially cold winters, where protection from freezing winds won’t be a problem.
Underquilts come in all shapes and sizes.
How tall are you? Do you want an underquilt that will insulate the full length of your body or are you willing to sacrifice your lower legs?
Some people prefer to use a shorter underquilt and then put clothes or a small pad under their lower legs.
Underquilts don’t often work well with double hammocks – they’re really only designed for one sleeper.
If you plan on sticking two sleepers in a double hammock, your best bet would be to purchase two sleeping bag style underquilts and link them together, in order to form a double bag.
The sleepers will have more room, and the body heat can be shared evenly between the both of them.
Synthetic polyester or down?
Both have pros and cons.
Synthetic will still keep you a little warm if it gets wet while down is effectively useless once it’s wet.
But, this should be accounted for in the outer materials of a down quilt that should protect the down inner from any moisture.
Down is usually lighter and more compressible, but is also more expensive.
Also, as it is the plumage of ducks or geese, it’s not vegan and the debate is still out on how ethical the use of down is.
Responsible Down Standards exist so it’s possible to check whether the company you purchase from adheres to these standards.
On the flip side, down is biodegradable and naturally renewable so could be considered better for the environment.
While this isn’t an issue for car campers or those not carrying their gear far, if you want to use your underquilt on a backpacking trip, you’re going to want something light!
The weights of the underquilts on this list vary from around 25 to over 50 oz.
When you’re looking for the best hammock underquilt, the price is always a factor.
Price usually reflects quality but sometimes it’s worth being as objective as possible and weighing up whether you’re really getting more for your money.
Prices range from under $70US to over $200US – that’s a big range!
It isn’t worth spending a lot of money on a four-season underquilt if you only go hammock camping in tropical climates.
The perfect underquilt will both fit your budget and be designed for your favorite way to camp.
How to Make a DIY Hammock Underquilt
If you have even the most basic sewing skills and some determination, there’s no reason why you can’t make your own hammock underquilt, for cheaper and arguably more satisfying alternative to buying one.
Videos like below provide all the instruction you need to get started.
If you want to get really creative and eco-friendly, repurposing an old down sleeping bag could be a good alternative to buying new materials.
It’s literally a case of cutting to size (cutting through the middle of a baffle will probably be unavoidable so be prepared for lots of down and small feathers to be flying through the air), attaching elastic to the head and foot ends or gathering it with a drawstring, and then attaching cords to these gathered ends which will hook on the carabiners at either end of the hammock.
If you want an additional layer of warmth, foil safety blankets can be added to the mix.
And on that note…
…here are some great options to choose from:
