Are you in need of a warmer sleep system with a hammock underquilt?

Great, because we are ready to help you out.

No outdoor enthusiasts want to feel trapped indoors during the whole winter. Camping with only a warm sleeping bag and a hammock leaves you shivering all night long. Hammock underquilts are placed underneath the hammock so that the material isn’t compressed. It offers more bottom-bearing insulation than bag and hammock combinations do.

In our guide, we consider all the factors that make up a quality product. These include :

  • Down vs. synthetic insulation. Down is heavier but naturally water resistant. Synthetic is manufactured to be warm and compress down.
  • DWR treatments. Materials like polyester and nylon can be made more waterproof for temperamental weather.
  • Size and length. There are full size, half size, and ¾ size underquilts that provide different levels of comfort and compactibility.

Hammock Underquilts Buying Guide

Hammock underquilts need to be high-quality and well-designed for them to fulfill their purpose. Otherwise, you have spent over a hundred dollars, and your bum is still cold.

Here are 5 aspects to consider about hammock underquilts before buying one.

Down vs. synthetic insulation

There are two primary options for the material that companies use as an insulator for an underquilt. Down is a natural material, while synthetics can be several types of fabric.

  • Down is taken from certain birds, like geese. It is the layer of fluffy, soft feathers underneath their longer plumage. It is often water-repellant and the fluff that keeps these birds warm and below-freezing temperatures. Underquilts that use these include those like the Enlightened Equipment Revolt Underquilt, the Kammock Firebelly 30°F Underquilt, and as an option in the Aerie Underquilt from Outdoor Vitals.
  • Synthetic materials are typically polyester, hollow, or nylon with various denier ratings. Hollow cotton, like in the ODSE Lightweight Hammock Underquilt and the King Showden Hammock Underquilt, is yarn made with cotton and PVA fibers. At the end of the spinning process, the PVA fibers are dissolved, so it is only cotton with a “hollow” center since air is one of the best insulators.

Underquilt materials

The underquilt materials are different from the insulation interior. These are mostly polyester and nylon. Polyester doesn’t stretch out as much and is cheaper to produce. Companies use it to manufacture more affordable products.

On the other hand, nylon is more expensive to produce but also makes a more durable product. The weight depends on its denier rating.

Look past the material, though, to see how it has been augmented. Many products such as the Easthills Outdoors 3 Seasons Hammock Underquilt, are given a DWR coating. DWR stands for durable water repellent and increases the fabrics water shedding capacity.

Some products also have coatings that give it antimicrobial or antibacterial properties to stay safe no matter what you haul it through. The Snugpak Hammock Cocoon is an excellent example of this.

Wind can be the most significant factor in decreased temperatures. It winds its way through layers of clothing and wraps you up in it. Various products avoid this by having an additional lining made with material like polyester pongee, which is windproof.

The OneTigris Twilight Trekker Hammock Underquilt functions like this and still folds down to a small size.

Size and length

It might seem like a hammock underquilt would be the most effective if it extended the hammock’s entirety. Some companies have opted for different designs, though.

  • Full Length underquilts have more material built into them, and thus they have additional weight. They also typically have the lowest temperature ratings since they offer full coverage. These hammocks commonly cinch up at the top to stop any cold entering.
  • ¾ Length underquilts don’t quite extend to the top and bottom of the hammock, but theoretically cradle where your head and feet should end. They cinch to keep it warmer but don’t include the additional weight from extra fabric. The Western Mountaineering SlingLite is designed like this.
  • Half Length hammock underquilts function almost like a blanket underneath and do not raise the temperature of a sleep system very much. They work for cooler weather and longer trekking trips.

Temperature rating

Temperature rating is perhaps the most important part of a hammock underquilt since keeping you warm is its job. Some are so thin, and they only help to keep you comfortable through one season.

Three or four-season quilts keep you warm throughout most or all of the year, no matter the weather.

Hammocks that only extend halfway only help warm up the center of the sleep system during cold weather. Examine what your needs are and the versatility of the underquilt.

Those that are rated lower are often heavier.

Take the example of the Revolt Underquilt. At 0°F rating, it weighs around 22oz. The same product but the higher-rated version of 50°F weighs in at only 7.8oz.

Decide which is more important: having a lightweight underquilt or being warm in freezing temperatures.

FAQ

Which is better, hammock underquilt vs. sleeping pad?

Most hammock campers believe that hammock underquilts are more comfortable than sleeping pads. Those who enjoy the hammocking experience don’t want something harder coming between them and the curve and fabric of the hammock. An underquilt is barely noticeable but adds the bonus of insulation.

Do I need a hammock underquilt?

You don’t necessarily need a hammock underquilt. However, if you are hammock camping in cool or cold weather, you will need bottom insulation. Hammocks should be breathable and airy. They don’t insulate, they cradle. Using a hammock underquilt gives you the hammocking experience while keeping you from harmful weather exposure.
