Do You Need an Underquilt for Hammock Camping?

Hammock camping has taken the outdoor world by storm. There’s something incredibly appealing about swinging gently between two trees, gazing up at the stars, and being cradled by nature itself. But hold up! Before you venture into the woods with your hammock, there’s one burning question you need to address: Do you need an underquilt for hammock camping?

Let’s dive into the nitty-gritty of hammock camping and explore why an underquilt might just be your new best friend in the wild.

The Basics of Hammock Camping

Hammock camping is essentially sleeping in a hammock instead of a traditional tent. Sounds simple enough, right? But anyone who’s tried it knows there’s a bit more to it than just tying your hammock between two trees and hopping in.

Why Hammocks Over Tents?

  • Comfort: Hammocks conform to your body, providing support in all the right places. Plus, there’s no sleeping on rocks or uneven ground.
  • Portability: Hammocks are typically lighter and take up less space than tents.
  • Versatility: You can set up a hammock almost anywhere there are trees, while a tent requires flat ground.
  • Cool Factor: Let’s be honest, hammocks are just cooler. Who doesn’t want to feel like they’re living out a Robinson Crusoe adventure?

Challenges of Hammock Camping

However, hammock camping isn’t all swinging and singing Kumbaya. There are some unique challenges, particularly when it comes to staying warm. Unlike tents, hammocks have no insulation beneath you, which brings us to our main topic: the underquilt.

What is an Underquilt?

An underquilt is essentially a blanket designed to hang underneath your hammock, providing insulation and keeping you warm. Think of it as a cozy sleeping bag for the bottom of your hammock.

How Does an Underquilt Work?

Here’s the science bit (I promise it won’t be boring): when you sleep in a hammock, the air circulates all around you, including underneath. This airflow can quickly sap the heat from your body, leading to a cold and uncomfortable night. An underquilt acts as a barrier, trapping heat and keeping the cold air at bay.

Why You Might Need an Underquilt

So, do you need an underquilt for hammock camping? The answer is a resounding yes—if you plan on camping in cooler temperatures. Let’s break it down further.

Temperature Considerations

  • Warm Weather Camping (Above 70°F): You might be able to get away without an underquilt. A sleeping pad or blanket might suffice.
  • Cool Weather Camping (50°F – 70°F): An underquilt starts to become more necessary. The nights can get chilly, and without proper insulation, you’ll be cold.
  • Cold Weather Camping (Below 50°F): An underquilt is essential. Without it, you’ll be in for a very uncomfortable—and potentially dangerous—night.

Comfort and Sleep Quality

Imagine trying to sleep while feeling cold air seeping through your hammock. Not exactly the relaxing experience you were hoping for, right? An underquilt ensures you stay warm and cozy, leading to better sleep quality.

Weight and Portability

Modern underquilts are designed to be lightweight and compact, adding minimal weight to your pack. Considering the comfort they provide, the trade-off is well worth it.

Alternatives to Underquilts

Of course, there are alternatives if you’re not sold on the idea of an underquilt. Here are a few options:

Sleeping Pads

Sleeping pads can be used inside your hammock to provide insulation. They are multi-purpose and can be used in a tent or on the ground as well.


  • Multi-functional
  • Usually cheaper than underquilts


  • Can shift around during the night
  • Less comfortable than an underquilt

Sleeping Bags

A good sleeping bag can provide warmth, but it’s not as effective as an underquilt in a hammock.


  • You probably already own one
  • Can be used for ground camping too


  • Compresses under your weight, losing insulation properties
  • Can be restrictive and uncomfortable in a hammock

Choosing the Right Underquilt

If you’ve decided that an underquilt is the way to go, here are some factors to consider when choosing one.

Temperature Rating

Ensure your underquilt is rated for the lowest temperature you expect to encounter. Better to be too warm and unzip than to be too cold.


Look for high-quality, lightweight materials like down or synthetic insulation. Down is warmer and more compressible, but synthetic is better in wet conditions.

Size and Fit

Make sure the underquilt fits your hammock properly. Many brands design them to be compatible with their hammocks, so check for compatibility.

Ease of Setup

Some underquilts can be tricky to set up. Look for one that has simple suspension systems and easy adjustments.

Setting Up Your Underquilt

Let’s walk through the basic steps of setting up an underquilt.

  1. Attach the Suspension: Most underquilts come with a suspension system that attaches to your hammock’s ends.
  2. Position the Underquilt: Adjust it so it hangs snugly underneath your hammock, without sagging or gaps.
  3. Tighten and Adjust: Use the provided cords and adjusters to ensure the underquilt fits snugly against your hammock’s underside.
  4. Test It Out: Hop into your hammock and make sure there are no cold spots. Adjust as needed.

CBS (Cold Butt Syndrome)

Ah, CBS – not the television network, but Cold Butt Syndrome. Anyone who’s spent a night in a hammock without proper insulation knows this all too well. Picture this: you’re snugly tucked into your hammock, enjoying the serenity of the great outdoors, when suddenly, an icy chill creeps up from below, attacking your derrière with a vengeance. This phenomenon, affectionately dubbed CBS, occurs because the hammock compresses your sleeping bag or pad, rendering it almost useless as a thermal barrier. The cold air circulates beneath you, creating a frosty bum that can turn a peaceful night into a shivering ordeal. An underquilt is your best defense against this chilly menace, wrapping your hammock in a warm, insulated hug and keeping CBS at bay. So, unless you enjoy the sensation of sleeping on a block of ice, do yourself a favor and invest in an underquilt.


Can I use an underquilt with any hammock?

Yes, underquilts are designed to be versatile and can be used with most hammocks. However, for the best fit, check compatibility with your specific hammock brand.

Do I still need a sleeping bag with an underquilt?

An underquilt provides insulation beneath you, but you’ll still need a top quilt or sleeping bag to keep warm above.

How do I maintain and store my underquilt?

Keep it dry and store it in a large, breathable bag to maintain loft. Avoid compressing it for long periods.

The Final Verdict

So, do you need an underquilt for hammock camping? If you plan on camping in anything less than balmy summer nights, the answer is a hearty yes. It can make the difference between a shiver-filled, restless night and a warm, comfortable, and memorable outdoor experience.
