How To Find The Best Hammock Underquilt

Best Hammock Underquilt

Generally it is considered that if you decide to take your hammock on a camping trip, you will be sacrificing some of additional comfort and warmth that comes with sleeping in a tent. However, that doesn’t have to be the case, thanks to underquilts.

For those that don’t know… What is a hammock underquilt?

A hammock underquilt is very similar a sleeping bag, but one that is designed to be used with a hammock. The underquilt provides insulation to the outside and bottom part of the hammock where you lose the most heat.

Underquilts work by creating a layer of air on the underside of the hammock which traps the warm air and keeps the cold air out. 

They are lightweight and the air spaces inside make them very compressible, packing down to the size of a water bottle.  

If you are planning on buying an underquilt for hammock, there are several factors that you will have to consider first. This article outlines the important aspects you need to know before making such a purchase, and provides a reviewed shortlist of the best 5 underquilts that we feel are worth your consideration.

Why use a hammock underquilt?

  • The bottom of your hammock will not provide enough insulation, especially if you’re camping in the cold season or on a windy night
  • Some campers may decide to spread a blanket or a sleeping bag on the inside of the hammock. However this won’t be anywhere near as efficient, since your body weight will compress the blanket, stopping it from holding any warm air. Underquilts are installed below the hammock so your weight does not affect its efficiency. 
  • If you still insist on keeping a sleeping bag at the bottom of your hammock, you may feel it shifting around as you sleep. This can be very uncomfortable. An underquilt remains in one position, providing an uninterrupted nights sleep.

Benefits of hammock underquilts

There are a few reasons why hammock campers choose underquilts to keep them warm:

  • Underquilts are installed outside your hammock and do their job without obstruction. You won’t get tangled up in one as you sleep and they don’t make it harder to get in and out of the hammock.
  • As mentioned earlier, underquilts are installed outside the hammock and your weight does not compress them. This means they can effectively keep you warm in any weather.
  • Most underquilts have a coating that makes them water repellent.
  • An underquilt can be used together with a hammock rain fly to give extra protection from the elements.

Disadvantages of hammock underquilts

In as much as there are perks to having a hammock underquilt, there are also some lows.

  • Underquilts can put quite a dent in your wallet thanks to their prices. Most of them cost between $50 and $300.
  • A sleeping bag will still be required as they don’t cover your whole body.

How to set up a hammock underquilt

If you don’t set up the underquilt properly, it won’t protect you from the cold as effectively as it should. It takes about 10 minutes to hang one. Here are the steps you should follow to get your underquilt up.

  • Spread out the underquilt and allow it to fluff.
  • Secure the ends of the underquilt to your hammock’s suspension system using the included suspension parts (carabiners or cords). 
  • Adjust the underquilt until the fluffiest part is directly below where you sleep.
  • Get into the hammock and adjust it until your whole body is covered, depending on the quilt type you have.
  • Cinch the quilt around the ends to prevent wind from getting in. 

Once all this is done, your underquilt should be ready to use. 

Underquilts vs sleeping bags & sleeping pads

Many campers might argue that it does not make sense to get an underquilt when you already have a sleeping bag. 

Underquilts make it easier to move around in the hammock. You also don’t have to worry about the underquilt shifting in the middle of the night. 

Sleeping pads and bags are placed between you and the hammock. As you sleep, your weight acts on the layer, making it nearly impossible for it to retain warm air. 

Considerations when buying a hammock underquilt

When in the market for an underquilt, there are some important features that you should keep in mind to ensure you are buying the right product…

Weight

For a camper, especially a backpacker, minimizing the weight of your load is essential. Most underquilts weigh between 20 and 50 ounces depending on their size, materials used to manufacture them, and the insulation type. 

It would be in your best interest to get the lightest hammock underquilt you can find. However, you shouldn’t prioritize weight over quality. If you are going to be camping in a relatively cold area, get an underquilt that is sure to meet all your needs, regardless of the weight. 

Outer materials

When it comes to choosing outdoor equipment, the materials used are vital in determining the durability of the product. It is no different when it comes to hammock underquilts. 

The material used depends on the temperature rating of the underquilt. Ripstop nylon is a popular option when choosing materials. Nylon dries faster when it absorbs water. However, it has the tendency to stretch with continued use.

An alternative to ripstop nylon is ripstop polyester. This material feels softer and is less susceptible to stretching.

You can also opt for an underquilt with durable water repellent material. This is a coating over the topmost layer of the underquilt. You would appreciate this feature if you find yourself in a rainy or drizzly situation

Fill material & loft

Your underquilt is only as efficient as the material used to create the insulation. Usually, an underquilt is filled with either down or synthetic material. If you are new to camping, start with a synthetic fiberfill as it is more pocket friendly. 

Polyester can keep you warm whether it is dry or not. It can also be used to manufacture a material called Primaloft, which is lightweight and water-resistant. It is preferred as an insulator due to its soft, light, hypoallergenic, and compressible properties.

Down is a natural material that also functions as an insulator. Down (a combination of bird plumage and feathers) from ducks and geese can be used, but duck down is a cheaper alternative. The down can be made to be water-resistant through a treatment process, giving rise to DownTek. This material dries quickly and takes in less water without compromising the lightness.

Loft refers to the fluffiness of the underquilt and it is measured in fill-power. The warmer an underquilt is, the higher the fill-power. 

Down vs synthetic

There are a few reasons why one would prefer one type of fill material to another. 

Down underquilts are lighter. This is because less down is required to trap the same amount of heat as a synthetic underquilt. They are also very compressible and would easily fit in a small space. 

A downside of these underquilts is their poor interaction with moisture. Down takes longer to dry out. Although variations like DownTek exist, they are still no match for the rain. 

Synthetic underquilts however, are more water-resistant and would offer more insulation in the rain. Their synthetic nature also makes it easier to wash.

Although they try, synthetic underquilts cannot offer as much insulation as down quilts without making them heavier. They are also bulkier and less comfortable.

Size and length

Hammocks come in different sizes and you will need to choose an underquilt that fits yours. If the underquilt is too narrow, you will feel uncomfortable and constrained. If it is too wide, it will let out all the warm air. Most manufacturers do not make underquilts for double hammocks, and you might have to buy two and join them. 

When it comes to length, hammock underquilts are available in two varieties; torso and full-length. 

Full-length underquilts cover you from head to toe. These are ideal for camping in the winter. A downside, however, is that they are heavier and bulkier. 

A torso underquilt is less bulky but it only covers the torso and excludes the arms and legs, you might have to use extra padding at the feet or wear thick socks. 

Temperature rating

This is also called the season rating. It determines whether your underquilt will effectively serve you when you decide to go camping.

A four-season underquilt is perfect if you plan on going camping in the winter. A three-season underquilt is the one for campers whose destinations are relatively warm. 

Water resistance

This feature keeps you and your underquilt dry in case it rains overnight. Some outer coverings are naturally resistant, like ripstop polyester. Some will need a water-resistant coating of DWR (Durable Water Resistant) or Nikwax.
