Camping in a hammock is the quickest and most comfortable way to enjoy a night under the stars. It’s difficult to find a place with a better view than from the gentle swing of a hammock on a brisk summer morning.
They are versatile, compact, and a great replacement for a tent or lean-to shelter. The one issue that arises when sleeping in a hammock is the fact that your rear end gets cold from the breeze underneath.
When the temperature begins to drop the breeze underneath the hammock will work its way through one or two layers with ease.
This is where the hammock underquilt comes into play. It’s another layer of insulation underneath the hammock preventing the cold from getting through. It rests on the outside of the hammock and adds insulation and another level of comfort on brisk evenings.
A hammock underquilt is an important piece of gear to use if hammock camping is your jam. If not, give it a try and see if it is something that sparks your interest.
What is a hammock underquilt
As the name suggests, it is a quilt that fits snugly inside of the majority of camping and backpacking hammocks. It’s basically a sleeping bag designed for use specifically with a hammock.
While a sleeping bag will work, often they are awkward to place inside a hammock and generally don’t fit that well. A hammock underquilt wraps the outside of the hammock creating an insulating layer that otherwise is open to the elements.
A good hammock underquilt is lightweight, compact, and extremely easy to pack. It should pack down into a size not much larger than a football and weigh under 3 lbs.
Do you need a hammock underquilt
Yes and no.
It ultimately depends on the time of year that you are using the hammock. If the temperature remains constant throughout the evening and doesn’t drop to a low temperature then a blanket will work just fine.
Sure, a sleeping bag or sleeping pad will work, however, they are not designed to rest inside the 30° curve of a hammock. By the middle of the night or the next morning, they are both going to be bunched up, twisted up, and pretty uncomfortable.
A hammock underquilt is designed to lay perfectly around the curvature of a hammock. This prevents uncomfortable bunching from occurring in the middle of the night and makes for a good night’s sleep.
If you are camping in the fall, winter, or early spring then a hammock underquilt is an absolute must-have.
Benefits of a hammock underquilt
The most important advantage is not freezing your ass off, literally. Hammock underquilts are built to keep your underside (ass side) well insulated throughout the evening.
Generally speaking, it is going to be a lighter option compared to a sleeping bag and sleeping pad. For the ultralight backpacker or anyone concerned with weight, a hammock with an underquilt is the lightest option.
In terms of setting up and breaking down, other than hanging your hammock it’s a fast and easy solution. You will have it up and ready in under 5 minutes once you find your desired location.
The first couple times that you sleep in the hammock may take some getting used to if you have never slept in a hammock before. After you get used to sleeping in a hammock it’s just as comfortable as the bed at home, if not more comfortable.

Hammock underquilt buying guide
Finding the best hammock underquilt is more than finding any old piece of fabric that you sling underneath your hammock. Things like temperature rating, insulation type, and size vary between the different underquilts.
We have put together a laundry list of questions and answers to make sure you find the perfect fit.
What type of insulation do I need?
Similar to sleeping bags there are two types of insulation that are commonly found in hammock underquilts, synthetic fill and down fill. They both do a fantastic job of keeping you warm and it comes down to a matter of preference and budget.
Down fill insulation is going to be warmer 9 times out of 10, however, the major drawback is it will not pack down as small as synthetics.
Synthetic fill may not be quite as warm as down, but where they shine is portability and weight. Synthetic insulation will pack into a smaller area making it a realistic addition for a lightweight backpacker.
What size do I need?
There are two main sizes…
- Torso length
- Full length
Torso length covers from the shoulder to the knees. They are made under the assumption that backpackers carry a small pad for sitting and chilling that can be used from the knees down while laying in a hammock.
Full length is exactly what it sounds like. It will cover the entire length of the hammock and eliminate the need for a pad hastily placed inside the hammock.
How heavy should the underquilt be?
As with every piece of backpacking gear, weight matters. Underquilts range from anywhere between 1 pound to 4 pounds. We always say the lighter the better, however, if extreme cold is in your future warmth should be the determining factor.
Not all underquilts are going to work for every hammock. Certain models are wider, while others are longer to accommodate the variety of sizes that are found in hammocks.
3-season or 4-season rating?
Just like a tent and sleeping bag, hammock underquilts have temperature ratings. If you are camping in the winter a 4-season rating is an absolute must.
If you plan on encountering extremely cold weather conditions, make sure the underquilt is rated for 15° below the lowest anticipated temperature. These ratings are not always 100% accurate and having a buffer zone will compensate for unexpected temperature drops.
How durable is the underquilt?
As with anything you purchase, durability is always a huge concern. The last thing you need is an underquilt that rips after the first couple uses.
The ideal fabric anything ripstop that has reinforced seams and good reviews. Rips and tears are the most common damage done to 99% of all camping nd backpacking fabrics.
