The Best Hammock Underquilt On The Market [Review and Buying Guide]

Hammock campers often struggle with maintaining their warmth throughout the night, since the cold air is constantly coming into contact with the hammock’s underside. A regular sleeping bag and sleeping pad combination cannot save you from the cold in this situation, as these products are not designed to perform optimally in a hammock.

A hammock underquilt, on the other hand, will prevent you from waking up to the cold and help you get a full night of sleep. The underquilt drapes underneath your hammock prevent heat loss into the cold nighttime air, so that you can keep sleeping soundly under the stars.

While the winner of this product round-up is the Outdoor Vitals Aeries Down Underquilt thanks to its versatility and high-quality fabrics, there are multiple great underquilts that we will review and compare below. Read on to find the best hammock underquilt to keep you comfortable even on those chilly nights.

  • ►LIMITED LIFETIME WARRANTY: Here at Outdoor Vitals we believe you should get the high quality products you deserve. After you purchase, follow the simple instructions to activate your Lifetime Warranty!

The Outdoor Vitals Aerie Down Underquilt is the best overall option within this product round-up because of its versatility in many temperature rating options and uses, lightweight body style, compact size, overall warmth, lifetime warranty, and high degree of durability and practicality.

With the Outdoor Vitals Aerie Down Underquilt, you can choose from a 0, 15, or 45 degrees Fahrenheit temperature rating, so the quilt is versatile from mild to even colder evenings. The company advertises that their sleeping quilts have been thoroughly tested at 12,000-foot peaks in Utah to be within 5 degrees Fahrenheit of their stated temperature rating, so you can feel confident that you are purchasing a quilt that will live up to your expectations.

When selecting your Outdoor Vitals quilt, you can also choose the type of insulation filling you would like. 

The StormLoft 800-fill power down is a high-quality down, and, as it is coated with VitalDry DWR (durable water repellent), this down is more water-resistant in practical use than regular down would be. Couple this with the lightweight quality of down itself, and you have a remarkably lightweight, warm underquilt that will last for many years.

The other insulation option is 650+ fill power Hybrid LoftTek insulation, which is an excellent synthetic insulation that is extremely lightweight and compressible just like down, making it warmer than regular synthetic insulation. 

The Hybrid LofTek insulation is even more water-resistant than the StormLoft down, so synthetic insulation is still the best choice if you may meet some showers.

Both insulation types feature a “grid baffle design” that prevents the insulation from compressing too much. Thanks to this design, the Outdoor Vitals quilt is constructed in order to avoid cold spots from forming, making sure that you stay warm all night long. 

No matter which temperature rating and insulation option you choose, the Outdoor Vitals Aerie features a compact size that will fit easily into your hiking pack. With an outer shell made of 20 denier ripstop fabrics, the Outdoor Vitals quilt resists tearing and is built to last. The outer shell is also treated with the VitalDry DWR for even more water repellency. 

The Outdoor Vitals Aerie can also be used as a technical blanket for cold temperatures when hiking or caught in a storm. It also doubles as a sleeping bag, as it has a full-length YKK zipper that can fully enclose you. You can even purchase two quilts and connect them together to make a double sleeping bag.

Lastly, the company backs their quilts with a limited lifetime warranty and donates 1% of its revenue to projects aimed at reducing poverty worldwide.


  • Several temperature rating options available 
  • Can choose between synthetic and down insulation
  • Down is treated to be water repellent
  • Compact size
  • 20 denier ripstop fabrics in the outer shell, which is also hydrophobic
  • The purchase goes towards a good cause (reducing poverty)
  • Lifetime warranty

Main Benefits of a Hammock Underquilt

If you are camping on a chilly night and want to sleep cozily in your comfy hammock, a hammock underquilt is a valuable treasure to have. A hammock underquilt serves the purpose of keeping the underside of your hammock warm throughout the night by keeping drafts away. 

The under quilt is properly insulated to prevent heat from leaving your body through convection (heat loss into the air).

Underquilt vs Sleeping Pad or Sleeping Bag

While a sleeping pad and an underquilt have similar purposes (keeping warm at night), sleeping pads are not as useful in a hammock. 

When tent camping, a sleeping bag and sleeping pad combo may be the most practical option to keep you warm. However, many hammock under quilts also double as sleeping bags, so they are quite versatile. When hammock camping, though, there is no contest: a hammock underquilt is the best choice. 

Picture this scenario.

You’ve just finished a long day of camping, and you’ve finally set up your hammock and prepared for a night’s sleep. You’re cuddled into your sleeping bag on your hammock, and you fall asleep feeling warm enough. However, in the middle of the night, you wake up to find yourself shivering because your back feels too cold.

Then, thinking that you can solve this problem by placing a sleeping pad underneath your back, you quickly find that the sleeping pad doesn’t fit well and wants to slide out from underneath you. You smash it down some more and finally get it to stay put, but you still wake up feeling cold. This leads to quite a frustrating, restless night.

What went wrong?

The sleeping bag:

The truth is, a sleeping bag alone is unlikely to be warm enough for hammock sleeping. This is because as you lie on the sleeping bag and put your weight on it, the bag loses its ability to trap heat due to the air pockets in the bag being compressed. This exposes you to cold air underneath you. This is the same thing that happens when tent camping with only a sleeping bag, and it is why sleeping pads are so important.

More: The Best Sleeping Bag For Hammock For Hammock Camping

The sleeping pad:

Because sleeping pads are inflated, they won’t lie completely flat underneath your body, especially when you have a U-shaped hammock as a base. The uneven compression leads to cold spots. Also, the sleeping pad is likely to gradually slide out from under you, entirely defeating the purpose of using one.

You can avoid this entire scenario by using a hammock underquilt instead. The underquilt is designed to hang underneath your hammock, rather than between you and the hammock, so it does not get compressed and lose its ability to retain heat.

Because the underquilt will fit better with the hammock itself, you will feel more comfortable and sleep more soundly than you would if you attempted to use a sleeping bag and sleeping pad.

The hammock underquilt is constructed and designed specifically to keep you warm while hammock camping, so it’s the best choice for this scenario. Some underquilts are even made for a specific hammock model, making sure that they fit together perfectly for maximum heat retention.

Buying Guide: What to Look For in a Hammock Underquilt

Outer Materials

Hammock under quilts is usually made with nylon or polyester as the outer material. Often, you’ll see an outer shell made out of ripstop nylon, which is extremely tear-resistant, making the underquilt quite durable and long-lasting. Also, nylon itself is resistant to odor retention, so this makes for a more pleasant experience.

Nylon does retain water, so keep in mind that if it gets wet, it is likely to take a while to dry. This will make the underquilt much heavier to travel with. For waterproofing, look for a fabric called silnylon. This is a silicone-coated nylon that is also very durable but doesn’t retain water the way that regular nylon does.

Another common outer material for hammock underquilts is polyester, which is less strong than nylon but still fairly durable. Polyester does not retain water, so it is a better choice if you may be camping in moist conditions. You can also find polyester fabrics coated in silicone, called silpoly. This fabric is also very lightweight and windproof.

Fill Material and Loft

When picking out a hammock underquilt, one of the most important features to consider is the type of insulation that it is filled with. 

Down insulation:

Hammock underquilts with down insulation will be more lightweight and compressible, making them easier to travel with, as you can easily stuff them into your hiking backpack. 

Fill power is a measurement that indicates the weight or quality of the down. It measures how many cubic inches of loft (or puffiness, which traps air and warmth) is produced by 1 oz of the down. The higher the loft, the greater the amount of insulation.

In other words, the fill power measures how much warmth the down retains for its weight. Simply put, down with a higher fill power is more efficient at keeping you warm, meaning the quilt can weigh less to meet the temperature rating.

However, the drawback of down insulation is that it becomes heavy when it gets wet and takes a very long time to dry. The main problem, though, is that when wet, down does not retain heat successfully. Although you can find down that is coated to be water-resistant, it is not foolproof and will not keep you warm in soaking conditions.

More: NEMO Riff 15 Review

Synthetic insulation:

Quilts made with synthetic insulation will be heavier in general and won’t compress as much as a quilt made of down, so they are less easily packed away. 

Synthetically-insulated quilts are less efficient at keeping you warm and require more material to do so. For this reason, quilts made with synthetic insulation will probably be more challenging to hike with, due to their higher weight.

On the upside, synthetic insulation retains heat even when wet, so this is a better choice if there is a chance you may meet some rain.

Water Repellency

As we discussed, if you are looking for a hammock underquilt to use in inclement weather, synthetic insulation is your best bet because it will not lose its ability to keep you warm. 

If you are really set on a down quilt, though, look for one that has been treated with a hydrophobic (DWR, or durable water repellent) coating on the outside. This will help to repel some water and keep the down from losing its heat-retaining properties.

For the ultimate hammock camping experience, it’s important to make sure that you stay warm all throughout the night. This can be challenging because sleeping in a hammock allows the chilly night air to circulate all around you. A hammock underquilt is the perfect solution to this problem. 

The winner of this product round-up, the Outdoor Vitals Aerie Down Quilt, gains its title thanks to its water-resistant and durable fabrics. Its versatility is either a hammock quilt or sleeping bag, its efficient insulation types, and a lifetime warranty.
