hammock sleeping pad vs underquilt

Hammock camping is a fantastic way to stay close to nature and brave the elements. However, you still need to stay warm while you’re doing it: sleeping pads and underquilts can help.

Hammock Sleeping Pad Vs UnderquiltA sleeping pad is highly versatile and can be used in or out of your hammock. It provides warmth and padding and is affordable. However, underquilts provide wrap-around warmth and more versatility, but they are slightly heavier and pricier.

It’s not that simple, though. To determine which sleep aid is better I’ve combined my experience and research skills to create this detailed guide for you.

Sleeping Pad Pros and Cons

There are various types of sleeping pads, but the most common type for heat retention and a small pack size is the self-inflating pad. For that reason, I’ll be using that type of sleeping pad to determine the pros and cons below.

Pros

  • Beginner-friendly: Most beginners already have a sleeping pad for their tent, so it’s easy to start using it in the hammock, too
  • Extremely compact: Some sleeping pads can roll up into the size of a water bottle
  • Very light: Sleeping pads often weigh less than 3 pounds, although some can be heavier
  • Affordable: Some very high-quality sleeping pads are wonderfully budget-friendly
  • Hold heat well: High R-Value pads have great insulation

Cons

  • Not secure: Your sleeping pad can move around under you, and you might fall off it
  • Not breathable: If you sweat at night you’ll stay damp until morning
  • Very narrow: Your pad will often be narrower than your hammock so it will fit strangely

Underquilt Pros and Cons

Underquilts are designed to hang under your hammock rather than go inside it, so they’re quite different from sleeping pads.

Pros

  • Won’t move around: The underquilt is secured to the underside of the hammock, so you can move around and it won’t move with you
  • Highly insulated: All underquilts are well-insulated to keep heat loss at bay
  • Comfortable: You won’t feel the underquilt under you the way you’d feel a sleeping pad
  • Wrap-around warmth: The warmth comes up around your sides

Cons

  • Not the best for all hammocks: Some people have difficulty with underquilts in gathered end hammocks, but others find them difficult in bridge hammocks
  • Heavier than sleeping pads: Not great if you need to hit the trail with your gear
  • Pricey: You can get good pads for lower prices, but good underquilts don’t come cheap

Sleeping Pad vs Underquilt Weight

Winner: Sleeping pad

Sleeping pads are widely known in the camping community for being lighter than underquilts.

That said, some people don’t mind the weight difference. You may not mind, either. Your choice should be based on your needs as well as your preferences—that will help you determine if the higher weight of an underquilt is worth it for you.

However, sleeping pads don’t always win here. For example, regular self-inflating sleeping pads are much heavier than underquilts. Let’s compare products:

So, you have to be careful with your selection and choose an ultralight pad, as that’s what most experienced campers are likely to have. 

This Gear Doctors sleeping pad only weighs 1lbs 1oz, which makes it almost a whole pound lighter than the underquilt.

So shop smart! Two pads can have a similar R-value, thickness, and price while weighing enormously different amounts. Underquilts have less weight variation, so they’ll rarely exceed 2lbs, but that’s still heavier than some of the pads on the market.

Sleeping Pad vs Underquilt Comfort

Winner: Underquilt

I can’t tell you what you’ll find more comfortable, but I can tell you that I prefer underquilts. I feel like I have more freedom to move around without a pad, and I’m not afraid of slipping off the pad at night.

Lots of fellow campers agree.

Some people are still on the fence about the topic, and that’s fine. There’s not a huge difference between a pad and an underquilt to most people, but there are others that prefer the quilt enough to give up pads in hammocks for good.

I always recommend trying both options and seeing which one you like best. However, you should also take note of the pros and cons at the start of the article, as many of them will tie into how comfortable a pad is vs an underquilt.

Sleeping Pad vs Underquilt Warmth

Winner: It varies

It’s difficult to nail down which is warmer when it comes to underquilts and sleeping pads. Their warmth is measured in different ways, and it’ll vary per product.

Underquilts

Underquilts are often stated to be 4-season underquilts, winter underquilts, spring and fall underquilts, and more. They have different amounts of insulation in them, and it determines how much heat they’ll hold and how warm they’ll keep you.

Their main benefit in terms of heating is that they provide wrap-around warmth as they’re under you and they come up around the sides of the hammock. This is a benefit that sleeping pads lack. 

A lot of people figure out what underquilt they need for warmth via trial and error, and some find them warmer than expected while others feel they’re underwhelming.

However, sleeping pads are far easier to pick in terms of how warm you’ll be.

Sleeping Pads

Sleeping pad insulation is measured on a scale known as R-value.

Here’s a helpful table:

Range60°F/16°C40°F/4°C20°F/-7°C0°F/-18°C-20°F/-29°C-40°F/-40°C
R-Value0.5-11.5-22.5-33.5-44.5-55.5-6

If you want to go deep into how R-value works, you can read that here.

Basically, when you read the R-value of a sleeping pad, then you know what temperature conditions you’ll be able to withstand. You might be chilly, you might be “okay”, or you may be extremely warm depending on the rest of your sleep setup.

Experimenting with different sleeping pads and underquilts is the only way to figure out which one is warmer for you.

Sleeping Pad vs Underquilt Versatility

Winner: Underquilts

A lot of people feel that sleeping pads are more versatile than underquilts, and this is true in a way. Sometimes you’ll be camping and you won’t find a suitable area for your hammock. You’ll be able to use your sleeping pad on the ground in this case.

However, that’s all you can use your sleeping pad for in most cases. You can only use it to sleep on top of it whether you’re in your hammock or not.

Underquilts are much more versatile than that.

Can you sleep on an underquilt if you can’t use your hammock? You could, but I won’t recommend it. But you can use it on the ground in other situations. Let’s look at what else it can be used as:

  • Picnic blanket
  • Used as an overquilt if you lose/forget yours
  • Emergency shelter from the rain if nothing else is available
  • Extra blanket for sleeping
  • Shawl to wrap around you if your jacket isn’t warm enough during the day

Sleeping Pad vs Underquilt Packed Size

Winner: Sleeping pads

The packed size of these products varies. To keep this fair, let’s compare the light sleeping pad and the underquilt from earlier.

The Gear Doctors sleeping pad packs extremely small to only 8.5 inches long and 3 inches in diameter. Many inflatable and self-inflating sleeping pads can pack down to a similar size.

The RAND TRUNK 360 ThermaQuilt is around 15 inches long and 23 inches in circumference when it’s in its stuff sack. This is average enough, with many other underquilts compressing to similar sizes.

There’s a lot of fabric in an underquilt, so the packed size will always be larger than most sleeping pads. Foam sleeping pads are the exception, as they roll up into long tubes and they’re much bigger than underquilts when packed.

Sleeping Pad vs Underquilt Convenience

Winner: Underquilts

Convenience is another subjective factor. Let’s look at the few facts associated with it:

  • You can fall off sleeping pads, but not underquilts
  • It can be difficult to get into a hammock when there’s a sleeping pad moving around in it
  • Attaching an underquilt to a hammock is mostly easy
  • If your sleeping pad is punctured you’re out of luck, but it’s easy to lay an underquilt into a hammock if the strings that attach it to the hammock snap

It looks like underquilts take the lead in terms of convenience when you think about it in specific scenarios.

The size and weight of both pieces of equipment also factor into their convenience factor, so keep that in mind when you’re choosing a product based on how easy it is for you to use.

Despite underquilts seeming to be the winner here, you can make sleeping pads a little easier to use in your hammock. It’s time to ask, should sleeping pads go inside sleeping bags?

If you place one inside your sleeping bag then you won’t fall off it, it won’t move around, and it’s unlikely to be punctured whether you’re on the ground or in the hammock.

Sleeping Pad vs Underquilt Price

Winner: Sleeping pads

Sleeping pads are generally the most cost-effective option.

There are sleeping pads and underquilts available at various price points. If you do a general search without being brand-specific, then you’ll find both products ranging anywhere from $30 to over $100.

The quality difference at different price points and between brands will vary, so let’s look at a popular brand for camping gear: REI.

REI underquilts are all over $100 and go up as high as almost $300. They’re expensive because they’re long-lasting and high-quality, and there’s a huge performance difference between a REI underquilt and an inexpensive one from any other brand.

REI sleeping pads have a much lower price tag. Some are under $50, but they’re the very thin ones. They inch towards $100 as they get thicker, and many of the highest-quality pads are over $100. 

There are a few pads over $200, but any over $300 are double sleeping pads. With the lower price for the quality and the wider price range available, sleeping pads are by far the more affordable option.

Do I Need a Sleeping Bag With A Sleeping Pad?

You don’t need a sleeping bag with a sleeping pad. You can use a wool blanket or an overquilt instead. However, using a sleeping bag is highly recommended as they’re well-insulated and work particularly well in colder weather.

When comparing a sleeping bag vs sleeping pad, I determined that you’ll have the best time if you use both pieces of gear, but you can go without one or the other if the situation calls for it. 

Use your best judgment about how cold and comfortable you’ll be if you choose to go without one or the other.

Do I Need a Sleeping Bag With An Underquilt?

Using a sleeping bag with an underquilt is recommended but not necessary. You’ll need some kind of protection from the cold over you, but you can use a blanket or overquilt instead. 

Sleeping bags add extra padding, and you don’t always need that padding in a hammock. The bag is really there to add warmth.

That said, a little extra padding under the weight of your body isn’t going to hurt, and it may make you feel more comfortable even if you weren’t uncomfortable without one.

Are There Any Alternatives to Sleeping Pads and Underquilts? 

There are plenty of options for you if you dislike both sleeping pads and underquilts. You may have to get a little experimental, but these alternatives can get the job done.

Sleeping Bags

You can use a thick winter sleeping bag without anything else in a hammock, but you may end up feeling too cold underneath. There’s a lot of cold air that can circulate under your hammock, and it won’t feel very nice if there’s a chill under your body.

Emergency Blankets

Emergency blankets are designed to reflect body heat back to you, so using a few of them in your hammock can help keep you warm. You can sleep on top of one of them and place another over you like a quilt. 

Wool Blanket

People often think of wool blankets in the context of wool blanket vs sleeping bag, but you can use a blanket with or without a bag while you’re in a hammock.

Laying a wool blanket into the hammock adds further protection from the cold, so it’s a great alternative to a pad or underquilt. They’re not the thickest things in the world, but some insulation is better than none.

Overquilt

Overquilts have lots of padding and insulation so they can make you warmer and more comfortable. Although they’re designed for use on top of you, you can still use them underneath you. 

Line the inside of the hammock with the quilt, then get on top of it. It may move around a little, but the parts that are under you will stay in place.

Who Wins?

There’s no clear winner here, but there are certainly winners in different categories that you can use to determine which sleep setup would be better for you.

People generally prefer underquilts, and it’s not hard to see why, but there’s also a great argument to be made for using a sleeping pad instead. 

At the end of the day, there’s no right answer. But I hope the criteria above has given you enough information to make the right choice for your circumstances.
