10 Best Hammock Underquilts for Backpacking

A guide to the best hammock underquilts for ultralight backpacking and camping.

Updated on May 30th, 2022

Using an underquilt with your hammock adds insulation to keep you toasty on cold nights. Hanging on the outside of your hammock allows the quilt to stay fully lofted and remain securely in place. For these reasons, it’s a far superior option to using a sleeping pad or bag in your hammock.

We tested the best hammock underquilts available in 2022 and provided our top picks below along with our buying advice. In this article, we will also break down how to use an underquilt and some FAQs.

The Warbonnet Wooki has a unique design to keep you warmer than a traditional underquilt. The blanket portion is sewn into a piece of fabric that extends the length of the hammock. It's like a hammock with a blanket.

Because it covers the entire bottom of the hammock, you stay warm from head to foot. Built to last, the Wooki is made with 20D ripstop nylon, and 850 fill Hyper-Dry DWR goose down. The outside fabric is treated with a DWR coating that adds a water-resistant layer to protect from light rain and morning dew.

Weight: 13 ounces

Material: 15 Denier Water-Resistant Nylon

Insulation Type: Goose down

Fill Power: 850

Temperature Rating: 20°F

Length: 74 inches

Price: $305

Why we like it: At 13 ounces and a 20F temperature rating the Slinglite is a go-to for those unwilling to sacrifice weight or performance.

Western Mountaineering started 30 years ago as a small independent company, and it remains one to this day. The company carefully sources its materials and crafts them to make some of the highest quality bags on the market.

The Slinglite Underquilt weighs a mere 13 ounces, adding less than a pound to your pack for warmth down to 20°F. The company's winning combination is its ultra-light 15D water-resistant nylon fabric and 850 fill down. It has a continuous baffle design for optimal loft and warmth.

The Slinglite uses shock cord ends and clips that allow you to attach it to any hammock regardless of manufacturer. Elastic draw-cords at the head and foot reduce drafts and improve warmth by keeping the quilt snug on the hammock.

Outdoor Vitals StormLoft

best hammock underquilts outdoor vitals stormloft

Weight: 20 - 32 ounces

Material: 10 Denier Ripstop Nylon w/ VitalDry DWR

Insulation Type: StormLoft™ DWR Treated Down

Fill Power: 800

Temperature Rating: 30°F, 15°F, 0°F

Length: 75 inches

Price: starts at $229.97

Why we like it: The StormLoft’s balance of weight, cost, and temperature rating make this a solid buy.

Like many outdoor companies, Outdoor Vitals was founded with an unrelenting passion for ultralight gear and a desire to bring this gear to a broader audience. Outdoor Vitals wants outdoor enthusiasts to "live ultralight" by buying less equipment that'll last longer and go further. The company also strives to keep costs low by selling directly to the consumer. This dedication to craftsmanship and affordability is evident in the company's StormLoft underquilt.

The StormLoft covers you from head to toe with warmth and comfort. The 800-fill down provides plenty of heat-trapping loft for colder temperatures, while a unique vertical baffle helps keep the down right where you need it most. A contoured cut also helps to warp the quilt around you when you climb into your hammock.

The StormLoft has an integrated suspension system that easily attaches to a variety of hammocks. There's also an extra draft baffle and bungee adjustments that let you seal out any drafts. On the outside, the underquilt is made with ultralightweight 10D ripstop nylon that helps keep weight to a minimum.

Hammock Gear Economy Phoenix

best hammock underquilts hammock gear economy phoenix

Weight: 13.4 - 23.5 ounces

Material: 20D Calendared Nylon Taffeta fabric

Insulation Type: DWR Treated Grey Duck Down

Fill Power: 800

Temperature Rating: 40°F, 30°F, 20°F, 10°F, 0°F

Length: 54 inches

Price: starts at $169.95

Why we like it: The Phoenix’s ¾ length keeps it inexpensive and lightweight, perfect for 3-season backpackers looking to trim ounces.

Based out of Columbus, Ohio, Hammock Gear has assembled a team of experts to help design and manufacture their line up of hammock gear and accessories. The company cuts costs by selling directly to customers without a retailer in the middle to jack up the price. They are best known for their affordable hammock gear with down underquilts available for less than $200.

The Economy Phoenix underquilt starts at $110 for a 40°F and climbs to a mere $190 for a 0°F quilt. The Phoenix is a 3/4-length underquilt measuring 52-inches long and 45-inches wide. It is designed to cover the core of your body (shoulders to knees), so you will need a small sit pad or piece of insulation under your feet.

To maximize insulation power, the Phoenix is filled with 800-fill DWR down and is shaped to contour your body when you sleep in a hammock. Adjustable corded ends ensure a no-draft fit. The hammock is made with a 20D nylon taffeta that is soft and silky on the skin.

Not only is the Phoenix low in price, but it also is low in weight. It is an ideal underquilt for the three-season backpacker who wants to trim ounces without sacrificing warmth or comfort.

Simply Light Designs Trail Winder

Simply Light Designs Trail Winder

Weight: 20.2 ounces (asymmetric orientation)

Material: Argon 90 Nylon

Insulation Type: Apex Climashield synthetic insulation

Fill Power: N/A (Synthetic)

Temperature Rating: 30F

Length: 106 inches

Price: $170

Why we like it: The ultimate customizable option for experienced hammock users at a low price point.

A unique feature of the Trail Winder is the asymmetric orientation option. This saves space and weight by cutting the synthetic insulation at an angle based on how you sleep in your hammock. For example, head left, feet right, or visa-versa. There is also an option to order a standard, full width, cut if you switch your sleeping orientation.

The average weight is impressive given it’s made from heavier, but more water-resistant, synthetic fill. The sheer number of customizable options can be overwhelming for new hammock users.

Hammock Gear Econ Incubator

hammock gear econ incubator

Weight: 21.6 ounces

Material: 20D nylon taffeta with Nikwax® DWR

Insulation Type: Nikwax® DWR treated duck down

Fill Power: 800

Temperature Rating: 30F

Length: 78 inches

Price: $190

Why we like it: Durable, with a low price point for a down-filled underquilt.

If you’re looking for a down underquilt, the Hammock Gear Econ Incubator offers one of the lowest price points on our list. At 21.59 ounces (30F version), it is on the slightly heavier side for a full-length underquilt. The down and 20D nylon shell are both treated with a DWR allowing this underquilt to hold up well against the elements.

The clipping system can be tricky, but after practicing it works well with most hammock setups. If you want customization, Hammock Gear has many options to tweak the design to your needs.

Arrowhead Jarbidge River Underquilt

Arrowhead Jarbidge River Underquilt

Weight: 20 ounces

Material: 30D ripstop nylon with DWR

Insulation Type: Apex Climashield synthetic insulation

Fill Power: n/a (synthetic)

Temperature Rating: 25F

Length: 58 inches

Price: $109

Why we like it: At just over $100 the Jarbidge is an extremely good value underquilt.

The most notable feature of the Jarbidge River quilt is the low price. Especially noteworthy because it’s competitive with the other underquilts on our list with a temperature rating of 25F and a 20-ounce weight.

To achieve the low cost, the Jarbidge River uses a Climashield Apex synthetic fill. The fill is heavier but more water-resistant than down. The weight savings comes from making the underquilt only 58 inches long. Most users will need to add a pad under their feet or neck to get full insulation in colder temperatures.

Considerations

WEIGHT: Keep it under 2 lbs.

Underquilts are available for backpacking, car camping and even at home use. Keep the weight comparable to a similar temperature-rated sleeping bag. Weight is obviously one of the biggest considerations when backpacking so aim for a quilt that is about 30 ounces or less if you are looking to pack light.

hammock underquilts

MATERIAL: Know the difference between nylon and polyster.

The outer shell of an underquilt is made with either synthetic nylon or polyester fabric. Ripstop nylon is the most common. The stretchy, durable fabric doesn’t tear easily. Nylons used for underquilts are often treated with a DWR (durable water repellent) to help repel water in damp conditions. Polyester is less stretchy and doesn’t absorb water. The downside is it’s not as strong as nylon.

outdoor vitals stormloft
Outdoor Vitals Stormloft is made with ultralightweight 10D ripstop nylon

Underquilts are suspended below your hammock meaning they shouldn’t be coming into contact with the ground. Because of this, they can be made of thin layers of nylon or polyester to save weight since they encounter less abrasion from the ground.

SIZE AND LENGTH: Do you need the extra insulation coverage for colder conditions?

Underquilts are typically sold in full, half and three-quarter length sizes.

  • Full-Length: The full-length size is bulkier and heavier than the shorter quilts, but they provide head to toe protection. It is excellent for cold sleepers or hammocking in the winter.

  • Half-Quilt: At the opposite end of the spectrum is the half quilt which covers only your midsection. It is reserved for ultralight backpackers who want the most minimalist gear possible.
  • 3/4 Length: The three-quarter length quilts hit the sweet spot between comfort and weight. These quilts are not as heavy as a full-length, but not as lightweight and sparse as a half-quilt. The three-quarter quilts cover you from your head to your knees, providing just enough warmth so you can sleep. You may have to stick a small pad under your feet or wear extra warm socks to keep your toes warm on a chilly night.

INSULATION: Down (feathers) versus synthetic fillers. 

Down: 

If you are going to be backpacking in mostly dry conditions, then down quilts should be your first choice for your sleep kit. Down underquilts are lightweight, compress easily, and are very warm for their weight.

When researching, you'll see the 'fill power' of a quilt. Fill power is a measurement of the loft quality of the down. The higher the fill power, the higher the loft of the down and the more warmth the down will deliver.

hiker using a hammock underquilt

The fill power influences the weight of the quilt. A higher fill power down will require less down to meet its temperature rating and will be lighter in weight than a lower fill down. Most ultralightweight down quilts use 800-fill-power or higher down and weigh 3 pounds or less.

Down is warm and lightweight, but it has a significant downside. When it gets wet, it loses its loft and its ability to keep you warm. Some down is treated with DWR to repel water and minimize this loss of heat, but it only lasts so long. If you get caught in the soaking rain, even DWR won't help keep the down dry and you warm.

Synthetic: 

Though down is the most common insulation, you sometimes will see underquilts made with synthetic insulation. Though heavier than a down quilt, a synthetic underquilt excels when it is wet. Because of how it is made, synthetic insulation will retain warmth even when it is wet, making it ideal for hammocking in inclement weather or moisture-prone areas. A synthetic quilt will be heavier to carry and won't compress down, making it bulky. It's a trade-off you have to make if you want to be warm when it is wet.

TEMPERATURE RATING: Consider your trip temperatures and add a 'buffer'.

Like sleeping bags, most underquilts have a temperature rating that is often listed as a comfort rating or a limit rating. The comfort rating is the lowest temperature that you could stay warm while sleeping or resting in a relaxed state. The limit rating is the lowest temperature you could not get cold when curled up in a ball to sleep. The comfort temp is the target temperature while the limit is the absolute bottom temperature you should use the bag.

hiker sipping coffee while using a hammock underquilt

These ratings are only guidelines. Everyone sleeps differently - some people sleep cold while others sleep warm. Choose a bag that has a comfort rating that matches the most frigid conditions you'll encounter. If you are a cold sleeper, then add a 'buffer' - or go 10 degrees lower than your coldest outdoor temperature. For most people, a 20°F quilt is more than enough for three-season use, while cold sleepers should consider a 10°F quilt. If you are only doing summer camping, then you could go a bit warmer and choose a 30°F or warmer quilt.

WATER RESISTANCE: Waterproof coatings are nice, but care is more important.

Down can't handle moisture, but there are ways you can minimize exposure. You can purchase a quilt treated on the outside with a DWR coating or internally with a water-resistant down. Both methods help to repel water and keep it away from the fragile down fibers that clump when they are wet.

More important than coatings is how you care for your quilt during the day as you hike and at night while you're set up. In the daytime, ensure your quilt is stored in your pack with a dry pack liner or in a dry stuff sack. At night, ensure you know you have dry weather conditions or that your rain fly has adequate coverage.

SUSPENSION SYSTEM: Simple setup is ideal.

Underquilts are positioned underneath your hammock and must be adequately attached if you want them to keep you warm. The hammock must first connect to your hammock's suspension systems using a shock cord and micro-carabiners or cord lock.

hiker using hammock underquilt

This attachment allows you to position the quilt underneath the hammock and up around the sides as needed. You'll want the quilt to be snug underneath you but not so tight that you compress down the quilt and prevent it from lofting. This loft traps heat and will keep you warm.

Once the quilt is hanging correctly, you then need to use the cord locks or a similar system to cinch down the head and foot portions of the quilt to prevent sleep-stealing drafts.

Why Use a Hammock Underquilt?

Why use a hammock underquilt? Because hammock underquilts add serious insulation to your hammock setup for a warmer night's sleep.

It only takes one cold night to realize that using a sleeping bag in a hammock might not be ideal. The issue is compression. When you are laying on your back in the hammock, you are compressing the insulation of the sleeping bag.

sleeping hiker using a hammock underquilt

Without air pockets to trap heat, this compressed part of the bag stays cold and you have a terrible night's sleep. You can throw a sleeping pad under your back for added warmth (double layered hammocks help with this), but that often doesn't work. Most sleeping pads don't fit inside a hammock and easily slip out when you are sleeping.

hiker using a hammock underquilt

A better alternative is the underquilt which hangs snugly underneath your hammock. Because it hangs on the outside of the hammock, the underquilt is not compressed. It can loft and provide warmth along your back. Underquilts can be used four all year round, but are most useful in the fall and winter when temperatures drop.

How to Set Up an Underquilt

Hanging an underquilt takes less than ten minutes, but you need to get it correct, so you are not cold while you are sleeping.

✓ Step 1: Unpack the underquilt, allow it to loft, and locate the two ends of the quilt.

✓ Step 2: Attach the two ends of the underquilt to your hammock suspension system using the included shock cord, carabiners, or cord locks.

✓ Step 3: Adjust the underquilt backward and forward, so the loftiest section is positioned directly underneath where you sleep.

✓ Step 4: Climb into the hammock and tweak the placement of the quilt to ensure your head, torso, and feet are covered by the quilt (if you have a full-length hammock).

✓ Step 5: Adjust the elastic at the head and feet to cinch the quilt around each end of the hammock to prevent drafts.

FAQs

How to make an underquilt for a hammock?

You can make a DIY underquilt using an extra sleeping bag or pick up a cheap 700-fill down throw for less than $50 from Costco. Designs for a DIY underquilt range from the relatively simple no-sew quilt to the more complex quilt with shock cord loops and sophisticated suspension attachment.

You do have to be able to use a sewing machine and must know how to work with standard sewing supplies like seam rippers and grosgrain ribbon.

hiker adjusting hammock underquilt

Basic steps to turn a Costco blanket into an underquilt:

  • Step 1: Place the blanket's shiny side up.
  • Step 2: Create baffles along the short ends. Use a sewing machine to stitch down.
  • Step 3: Create baffles along the long sides. Stitch along the crease.
  • Step 4: Attach webbing to the long sides.
  • Step 5: Add the bungee cords and toggles. Adjust tightness if needed.
  • Step 6: Position under your hammock like you would a store-bought underquilt.

Hammock underquilt vs sleeping pad - which is better for hammocks?

Sleeping pad is better than a hammock underquilt. A Hammock underquilt and a sleeping pad serve a similar purpose - both add insulation and warmth underneath you as you sleep. Sleeping pads, however, are more versatile. You can use them in a hammock or on the ground. They also are affordable if you don't already have one.

hiker using a hammock underquilt

Sleeping pads in a hammock pose some challenges. First, they typically are narrow and difficult to sleep on in a hammock. Unless you attach it to your hammock or your sleeping bag, you will likely slide off the sleeping pad or have it slip out of your hammock. You'll realize you lost your pad when you wake up cold in the middle of the night.

hammock underquilt

Because an underquilt fits underneath your hammock, you won't roll off of it when you move at night and it won't slide off your hammock. Hammock quilts are designed to fit under a hammock so you can only use them with a hammock. You can't take t off the hammock and use it car camping or with a tent.

hiker sipping coffee

Underquilts tend to be more expensive than sleeping pads and less versatile, that's why they are popular among experienced hammock users who are willing to invest in gear. Sleeping pads are typical among first-time hammock sleepers who may not be ready to shell out $300 or more to try out hammock camping.

hiker using hammock gear econ incubator

Do I also need a top quilt?

Bottom quilts wrap your back in the warmth, but that is only half of your body. You still need to supply a layer of warmth on top of you. Most hammock users choose a top quilt to supplement their bottom quilt.

The top quilt is used as a standard blanket and is cut to fit conveniently inside a hammock. Just like a bottom quilt, top quilts are available in a range of temperatures and you should choose the best one for your conditions. During the summer, you may be able to get away without a top quilt, but they are a necessity in the winter.
