Best Overall Hammock Underquilt:

best hammock underquilts warbonned wooki


✅ Warm

✅ Lightweight


❌ Works best with other Warbonnet products


  • Weight: 10.5-23.7 ounces (0.66-1.48 lbs)
  • Material: 20D Ripstop Nylon with DWR
  • Insulation Type: Hyper-Dry DWR goose down
  • Fill Power: 850
  • Temperature Rating: 40°F, 20°F, 0°F, Scandinavian (-20°F)
  • Length: 76 inches

We like the Warbonnet Wooki’s unique blanket design which runs the length of the hammock. We found this offered more warmth than a traditional underquilt. The quilt uses 850-fill Hyper-Dry DWR goose down, the highest fill power we’ve seen in an underquilt. The 20D ripstop nylon fabric is treated with a DWR coating that adds a water-resistant layer to protect it from light rain and morning dew.

It’s available in several temperature ratings, many of which are some of the lightest on our list. Because of its excellent warmth-to-weight ratio and competitive price the Warbonnet Wooki is our best overall hammock underquilt.

Best Budget Hammock Underquilt:


Price: $119

Arrowhead Jarbidge River Underquilt


✅ Price

✅ Durability


❌ Shorter length


  • Weight: 20 ounces (1.25 lbs)
  • Material: 30D ripstop nylon with DWR
  • Insulation Type: Apex Climashield synthetic insulation
  • Fill Power: n/a (synthetic)
  • Temperature Rating: 25F
  • Length: 58 inches

The most notable feature of the Jarbidge River quilt is the low price, making it our best budget hammock underquilt. The price is especially noteworthy to us because it's still 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. We recommend taller users add a pad under their feet or neck to get full insulation in colder temperatures. The 30D nylon makes this a very durable option as well.

Best Premium Hammock Underquilt:

✅ Premium performance underquilt

✅ Ultralight

✅ High fill power


❌ Price


  • Weight: 15 ounces (0.94 lbs)
  • Material: 15 Denier Water-Resistant Nylon
  • Insulation Type: Goose down
  • Fill Power: 850
  • Temperature Rating: 20°F
  • Length: 74 inches

The Slinglite Underquilt weighs a mere 13 ounces, adding less than a pound to your pack for warmth down to 20°F. The winning combination for the Slinglite is an ultra-light 15D water-resistant nylon fabric and 850 fill down. We like that the continuous baffle design provides optimal loft and warmth.

It doesn’t come cheap, it’s the most expensive underquilt on our list. However, the Slinglite is a go-to for those unwilling to sacrifice weight or performance making it our best premium hammock underquilt.

Best ¾ Length Hammock Underquilt:

❌ ¾ length not for everyone


  • Weight: 13.8-22.8 ounces (0.86-1.43 lbs)
  • 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

The Economy Phoenix is our top pick for a 3/4-length underquilt. It measures 52-inches long and 45-inches wide and is designed to cover the core of your body (shoulders to knees). We recommend it in summer conditions. In shoulder seasons you may need to bring extra insulation for 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.

Not only is the Phoenix low in price, but it also is low in weight, which is hard to find in an underquilt. We recommend the Phoenix for the three-season backpacker who wants to trim ounces and doesn’t mind the ¾ length.

  • Weight: 21.6 ounces (1.35 lbs)
  • Material: 20D nylon taffeta with Nikwax® DWR
  • Insulation Type: Nikwax® DWR treated duck down
  • Fill Power: 800
  • Temperature Rating: 30F
  • Length: 78 inches

If you’re looking for an inexpensive down underquilt, the Hammock Gear Econ Incubator offers one of the lowest price points on our list. At 21.6 ounces (30F version), it is on the slightly heavier side though. The down and 20D nylon shells are both treated with a DWR allowing this underquilt to hold up well against the elements.

We found the clipping system tricky, but after practicing it we found it to work with most hammock setups. If you want customization, Hammock Gear has many options to tweak the design to your needs.

Outdoor Vitals StormLoft

✅ Fill power


❌ Durability


  • Weight: 10-17.6 ounces (0.63-1.1 lbs)
  • 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

The StormLoft covers you from head to toe with warmth at a minimal weight. We like that the 800-fill down provides plenty of heat-trapping loft for colder temperatures. And we found the unique vertical baffle helps keep the down right where it’s most needed.

The StormLoft has an integrated suspension system that we could easily attach to a variety of hammocks. The underquilt is made with ultralightweight 10D ripstop nylon which keeps weight to a minimum. The 10D fabric makes us question its durability, so treat it with care. StormLoft’s balance of weight, cost, and temperature rating make this a solid buy.

Enlightened Equipment Revolt

❌ Durability


  • Weight: 10.63-21.66 ounces (0.66-1.35 lbs)
  • Material: 10D interior / 10D exterior with DWR
  • Insulation Type: DownTek® treated down
  • Fill Power: 800
  • Temperature Rating: 40°F, 30°F, 20°F, 10°F
  • Length: 80 inches

The Revolt has an adaptable suspension system that is designed to accommodate a variety of hammocks, which is a big plus for us. It is wide (45-inches) and has a differential cut (the outer fabric is larger than the inner fabric), so we were able to pull the quilt snugly against the hammock without losing loft.

It is constructed with ultralight 10D nylon with a DWR coating. The 10D fabric is the thinnest on our list, making it less durable than others. The 850 down fill gives the Revolt an excellent warmth-to-weight ratio. Like all Enlightened Equipment products, we love that the Revolt is highly customizable to your needs.

  • Weight: 24 ounces (1.5 lbs)
  • Material: 20D Ripstop Nylon DWR shell, 33D Nylon Taffeta lining
  • Insulation Type: DownTek® water-repellent duck down
  • Fill Power: 750
  • Temperature Rating: 30°F to 40°F
  • Length: 82 inches

The Blaze underquilt is a full-length quilt with an adjustable fit that cinches at your head and feet. It has a 20D ripstop nylon outer shell and a 33D nylon taffeta making it one of the most durable options on our list.

On the inside, you'll find a 750-fill DownTek down that is water-resistant. The ENO is expensive, ranking near the top of our list in price. We also don’t like that it’s a heavy option, especially for a down quilt.

Simply Light Designs Trail Winder

Price: $169.95

Simply Light Design Trail Winder


✅ Price

✅ Highly customizable


❌ Weight


  • Weight: 33 ounces (2.06 lbs)
  • Material: Argon 90 Nylon
  • Insulation Type: Apex Climashield synthetic insulation
  • Fill Power: N/A (Synthetic)
  • Temperature Rating: 30F
  • Length: 106 inches

We found the Trail Winder to be a rather unique underquilt due to 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.

We found that even with the unique design, this is still a heavier quilt. We think the sheer number of customizable options is great for users who know exactly what they want in an underquilt but can be overwhelming for new hammock users.

Kammok Firebelly

✅ Versatility


❌ Weight

❌ Price


  • Weight: 28.2 ounces (1.76 lbs)
  • Material: Atmos X™ 15D ripstop nylon fabric with Cire, DWR waterproofing, and YKK snaps
  • Insulation Type: Downtek down
  • Fill Power: 750
  • Temperature Rating: 30°F
  • Length: 88 inches

The Firebelly quilt from Kammok is a versatile quilt that can be used as an underquilt or a top quilt. The Firebelly is a generous 88 inches in length, the second longest on our list. This provides ample coverage across your back as both a top and underquilt. The sleeping pad attachment lets you use it as a top quilt with a cozy footbox.

We found the 15D Atoms-X fabric, a proprietary material, is more abrasion-resistant and stronger than standard nylon. We don’t like that it’s more expensive and heavier than other underquilts. But if you want one do-it-all quilt the Firebelly delivers.

Key Factors To Consider When Choosing


Underquilt weight should be comparable to a similar temperature-rated sleeping bag. Fill material influences weight, with the down fill being lighter than synthetics. Thicker fabric will add weight too. We recommend a quilt that is 2 pounds or less if you are looking to pack light.

The lightest hammock underquilts are:


Fill material is the biggest factor in a hammock's underquilts price. High-fill power down comes at the most expensive price and is reserved for premium underquilts. Synthetic fills offer the lowest costs.

Hammock underquilts that provide the greatest value:

Affordable hammock underquilts:

Premium hammock underquilts (most expensive):


The outer shell of an underquilt is made with either synthetic nylon or polyester fabric. Ripstop nylon is stretchy, and the 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 but it’s not as strong as nylon. Because underquilts are suspended below your hammock they shouldn’t come into contact with the ground allowing them to be made of thin layers of nylon or polyester.

Most durable Hammock Underquilts:


The big choice for insulation is down vs synthetic. Down offers unbeatable warmth for its weight. It’s also highly compressible and packs away small. "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. The biggest downside? When it gets wet, down loses its loft and its ability to keep you warm. Synthetic insulation is heavier and less compressible. But synthetic insulation will retain warmth even when it is wet, making it ideal for hammocking in inclement weather or moisture-prone areas.

Other Things to Consider



How long should a hammock Underquilt be? How long a hammock underquilt should be is largely dependent on your needs and camping conditions. Underquilts are typically sold in full, half, and three-quarter length sizes.

  • Full-Length: 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.

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 in the bag.

These ratings are guidelines, everyone sleeps differently. What temperature do you need for a hammock underquilt? The temperature you need for a hammock underquilt should have a comfort rating that matches the most frigid conditions you'll encounter. If you are a cold sleeper, we recommend adding a 'buffer' - or going 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.

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.

This underquilt simply clips onto the hammock's suspension system



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?

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.

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.

Do I also need a top quilt?

You also need a top quilt when sleeping in a hammock. 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.

hiker using a hammock underquiltHow 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.

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

A hammock underquilt is better than a sleeping pad for hammocks.

hiker using a hammock underquilt

Both options serve a similar purpose - to add insulation and warmth underneath you as you sleep. An underquilt fits snugly underneath your hammock, which means you won't roll off of it when you move at night and it won't slide off your hammock.

hammock underquilt

 This makes it much better than a sleeping pad which is narrow and difficult to sleep on in a hammock. Underquilts also can be lighter and add more insulation than a sleeping pad.

If you’re new to hammock tenting or on a tight budget a sleeping pad can be used in a hammock in a pinch, just be prepared for a potentially awkward night of sleep.

How to make an underquilt for a hammock?

You can make an underquilt for a hammock using an extra sleeping bag or pick up a cheap 700-fill down throw blanket. 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 ribbons.

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.
