The Best Hammock Underquilt in 2021 – Warm, Cozy, and Worry-free

If you love the great outdoors and sleeping underneath the stars, a hammock is the only piece of camping equipment that could allow you to experience that to the fullest extent. 

However, when the colder months roll around, and the sun goes down, without additional gear that will keep you warm, your experience will end up being less than enjoyable. The thing about hammocks is that they lack any insulation, leaving your underside exposed to the cold weather

That’s where the best hammock underquilt comes in – a massive upgrade from the standard sleeping bag and pad combos, and the most effective option for hammock insulation!


Why Buy a Hammock Underquilt?

The best hammock underquilt will be an absolute must-have if you want to avoid CBS – the dreaded “Cold Butt Syndrome.

It’s silly, and you can laugh all you want. However, if you’ve ever spent a chilly night outside, you’ll know that what we’re talking about here is no laughing matter.

Besides, there are a few more notable advantages to opting for an underquilt as your go-to insulation method:

  • They’re designed to fit the curvature of your hammock perfectly. 
  • The insulating fill won’t get compressed – and therefore useless – underneath your weight.
  • They hug the hammock, and not you, so they don’t make you feel trapped.
  • They’re much more compact and lighter than a traditional sleeping bag and sleeping pad.

Thus, the ENO underquilt includes two layers of recycled and synthetic insulation, with a maximum temperature range between 40 and 60 F degrees.

OneTigris Hammock Underquilt

OneTigris is a well-known brand in the world of camping equipment – and the Night Protector is yet another addition to their already impressive lineup of high-quality products.

Plus, it won’t cost you a small fortune – it’s one of the more budget-friendly options on our list.

It’s made from synthetic materials inside and out. The SEE polyester fill is encased in the 20D rip-stop nylon shell with a high-quality DWR coating, which gives the underquilt its water-repelling properties.

It measures 7.9 by 4 feet when fully extended, but compresses neatly into the included stuff sack. And considering that it weighs a mere 28 ounces, it qualifies as lightweight and compact, too.

The official temperature rating of this underquilt is between 68 and 40 degrees Fahrenheit, so it’s meant to handle temperature drops rather well. If you want a three-season hammock camping companion to keep you warm, this one should be right up your alley.

One downside of the Night Protector is that it isn’t contoured as some other models you’ll see today. That could result in it feeling a bit stiff against your body. However, it’s affordable, easy to use, and offers optimal insulation, so it's a trade-off we’re willing to take. 

  • Features a 20D rip-stop nylon shell and SEE polyester fill
  • The three-season temperature rating for 40 to 68 degrees Fahrenheit
  • Easy to use with included setup accessories
  • Relatively lightweight and compact
  • Comes with a lifetime warranty
  • Not contoured by design
  • Some warmth escapes on the sides

OneTigris Shield Cradle Double Hammock Underquilt

Last, but not least, we’d like to give you an insulating option for your double hammock. You and your sleeping partner can’t rely solely on each other for warmth, now, can you?

And before you get a chance to ask, yes, the Shield Cradle has a lot to offer besides the spacious, 8.2 feet by 5.6 feet design.

The outer shell is constructed out of 20D rip-stop nylon, has a DWR coating, and on the inner side of the underquilt, you’ll find the pongee lining of a 300T polyester. The secret is in the insulation, though – and that’s where the SEE polyester fill comes in and steals the show.

Overall, not only does it help retain heat and keep you warm but acts as a wind and water repellent, as well!

The “winter-friendly” version of this model has a rating for temperatures between 41 and 23 degrees Fahrenheit. Based on our experience, it does live up to that rating.

And while we appreciate that it comes with a four-point stuff sack, we couldn’t help but notice how bulky it is, even when fully compressed.

However, we don’t consider that to be a deal-breaker – this is a double hammock underquilt, after all. It’s not fair to compare it to those designed for single-sized hammocks.

  • Constructed out of 20D rip-stop, wind-proof nylon with DWR coating
  • Features a synthetic, SEE polyester fill
  • The 8.2 by 5.6 feet dimensions fit most double hammocks
  • Temperature rating of 41 to 23 degrees Fahrenheit
  • Comes with a four-point nylon stuff sack
  • It’s bulky, even when compressed

AYAMAYA Hammock Underquilt - Best Performance

Next off, this AYAMAYA underquilt will wow you with the best content. As you will notice, the unit includes a 20D rip-stop nylon shell full of DWR coating. Thus, the premium-quality material allows wear and tear and lasts for ample time.

Also, the 300T grade soft polyester lining with the imitation silk floss filing is everything! It’s comfortable, cozy, smooth, and warm, protecting you from various outdoor elements and extreme conditions. Thus, nothing will go wrong when you use this underquilt.

Thanks to the enormous proportions - 98.4 x 66.9 inches, wide sides, and great bottom, you will have enough room for a proper and more comfortable body posture and relaxing and cozy feeling.

So, the unit is excellent for an asymmetrical hammock, double hammock, large hammock, or a diagonal lay for maximum comfort when you use it as a single underquilt. In addition, it will keep you toasty and warm in chilly conditions.

On both ends, you can find short bungee cord loops for an easy and cozy fix for your hammock. It also comes with elastic straps, so the setup process is effortless. The unit doesn’t come alone, but with two large carabiners for more convenient use and setup.

The product fits all seasons and weather conditions, and the temperature ranges between 20 and 68 degrees F easily. It will keep you warm, cozy and comfortable during all periods. However, it’s not recommended for a harsh winter.

You will find a compressing suck for more storage space and better portability.

Outdoor Vitals Aerie 0 15 30 45 Degree Down Underquilt - Highly Versatile

Our round-up of the best hammock underquilts continues with a high-quality, multi-functional model designed by Outdoor Vitals – and easily one of the most versatile options on the market, too.

Besides being a camping hammock underquilt, thanks to its versatile design, it boasts three other potential uses. Depending on how it’s set up, it functions as a single or double sleeping bag, a technical blanket, or a hammock pod system.

The Outdoor Vitals has a low-temperature rating of 20 degrees Fahrenheit, which makes it an excellent addition to your winter hammock camping gear.

And even though it provides exceptional insulation, it’s still relatively lightweight, weighing a little over two pounds. The secret is in the combination of light, yet durable materials:

The underquilt features a 20D rip-stop nylon shell, complete with the VitalDry DWR coating, to ensure that you’ll stay warm and dry, despite what the weather conditions are. Inside, you’ll find the 800+ power natural down fill, also covered with a hydrophobic coating, which makes it resistant to water and condensation.

Besides the minor issue of it not including any hanging instructions, we don’t have much to complain about here. We love the concept, and we highly recommend it – as an underquilt, that is.

  • Highly versatile, five-in-one camping solution
  • 20D rip-stop nylon shell with DWR coating
  • 800+ fill power, DWR-treated down insulation
  • Rater for 20 degrees Fahrenheit
  • Comes with a four-point compression sack
  • Covered by a limited lifetime warranty
  • Questionable zipper quality
  • Doesn’t come with any instructions
  • Works best as an underquilt

Being perfectly cut and well-designed, it will fit all hammock types, serving as the highest protection during the cold weather. You could also easily set it up or take it down without any additional issues, as the unit provides the ultimate design and the most convenient use.

#8. Go Outfitters The Adventure Under Quilt - Best Material

Go Outfitters The Adventure Under Quilt - Best Material

Another option worth considering – and a reasonably priced one, too – is The Adventure Under Quilt by Go Outfitters.

Let’s start with the basics – the materials used in its construction. The outer shell features 210T rip-stop polyester that boasts water and wind-resistant properties. You’ll find the breathable 210T polyester liner on the inside, as well.

And even though synthetic fills sometimes fail to live up to their temperature ratings compared to natural down, the Max Loft synthetic insulation held its ground rather well. We’re confident in its performance enough to recommend pushing its 20-degree temperature rating to the limit.

However, what makes it unique is its fitted design with a permanent foot box, rather than the standard, go-to rectangular shape. Instead of having to make all the adjustments yourself, you can rely on its design to ensure a snug fit throughout the night.

At the same time, it’s surprisingly spacious, allowing for a genuinely diagonal body position – the key to staying comfortable while sleeping in a hammock. We highly recommend it to taller individuals.

Others, however, might find it hard to deal with all that “extra” material, so be sure to keep the 81-inch by 52-inch dimensions in mind.

  • A water and wind-resistant rip-stop polyester outer shell
  • Quick-dry, synthetic Max Loft insulation
  • It’s rated for 20 degrees Fahrenheit
  • Fitted design with a permanent foot box
  • Suitable for taller individuals
  • Compatible with all gathered-end hammocks
  • The shock cord is too thin and short
  • Might be too spacious for some

How To Pick The Best Hammock Underquilt: Buying Guide

You’ve seen what’s out there, so, now it’s time to answer that question that probably kept bugging you while you were reading our reviews: How do you pick the best hammock underquilt for your needs?

Here are the four vital factors to keep in mind as you narrow down your choices:

1. Material and Insulation

First of all, you’ll have to consider the materials used in the construction of your hammock underquilt.

High-quality rip-stop nylon shell, especially one that features water-repellant coating, such as DWR, is a highly recommended option. 

Next, you should check the insulating material. Your choice here boils down to two options that are commonly found in sleeping bags, as well – synthetic and down

  • Down: Nine out of ten times, natural down – made from plumage and feathers of ducks or geese – will prove to be a better insulator than its synthetic counterparts. Its warmth to weight ratio is virtually unmatched. However, it struggles with losing its insulating properties when it gets wet.
  • Synthetic: Designed to replicate all the qualities of natural down, minus its drawbacks, synthetic fill is a polyester-based fill option that retains its warming properties, even when wet. It tends to be the more portable option, ideal for hikers and backpackers, and a cheaper one, too. However, even the best synthetic down underquilts fall short insulation-wise when compared to natural down.

2. Weight

best hammock underquilt for the money

Most underquilts you’ll come across will weigh somewhere between one and four pounds, depending on their size, materials, and insulation type. And as with any other piece of camping gear, weight matters – a lot.

Always go with a lighter option – given that you’re not compromising insulation in the process, that is – as it will be easier to pack and carry. If you’re expecting extremely harsh weather and freezing temperatures, though, go with whatever feels warmer – weight should probably be the last thing on your mind.

3. Fit

Although they generally feature the same basic, rectangular shape, complete with shock cord suspension that allows you to adjust the underquilt to the contours of your body, not all of them end up being a perfect fit for all camping hammocks.

Since the key to retaining warmth is eliminating gaps between your hammock and your underquilt, finding one that is an appropriate fit is more important than you think:

It plays an essential – yet often overlooked – role in determining the efficiency of the underquilt itself, as well as your comfort level.

4. Temperature Rating 

Just like a sleeping bag, each hammock underquilt will come with a temperature rating. It’s a range of temperatures that it will perform the best in, including both the lower and the upper sleeping temperature limit.

Your choice comes down to two options – three or four-season ratings. 

If you plan on going camping in the harsh winter weather, we highly recommend that you get an underquilt rated for around 15 degrees below the lowest temperature you’re expecting to encounter. That way, you’ll have a “buffer zone” to compensate for any unexpected temperature drops or inaccurate ratings.

Frequently Asked Questions

Do I need an underquilt for my hammock?

YES, you will need one since it works as bottom insulation, and you could use it as a replacement for a sleeping bag. It will keep you warm and cozy; it will resist outdoor cold conditions and adjust significantly to your body posture and needs.

So, it’s a great choice if you plan to sleep outside during the night, as the unit will work as a blanket as well.

Do you need a sleeping bag if you have an underquilt?

Well, you can bring it, but it’s not necessary. The underquilt will act like a sleeping bag or a blanket and trap the heat to return it to your body. Thus, it’s more vital to have the underquilt to stay warm.

Many sleeping bags or blankets can act like top quilts, but an underquilt is always a better option.

How do you keep a hammock warm without an underquilt?

Some of the options include:

  • Using a sleeping pad
  • Using a reflective blanket to retain and return the hat to you
  • Using your old car’s sunshade
  • Stringing your hammock through your sleeping bag

Are underquilts universal?

Some of them are, such as ENO or Slinglite, which fit almost all commercial hammocks.

Regarding ENO, it won’t provide only SkyLoft hammocks, and you need to buy them separately. However, it will be a breeze for you to connect all parts and install the underquilts in the hammocks if you follow the instructions and procedure.

Who makes the best hammock underquilt?

All of the options listed above are perfect; they just vary in minor details.

However, the best recommendation is definitely ENO, as it includes the best design, performance, and quality and provides the best comfort and warmth while outside in the hammock.
