When you’re deep in the woods or hanging under the stars, there’s one thing that can make or break your night’s sleep in a hammock: staying warm. Enter the hammock underquilt — an absolute game-changer for comfort, insulation, and a restful night outdoors. Whether you’re a seasoned backpacker, a casual camper, or just enjoy backyard lounging, an underquilt can mean the difference between shivering all night and sleeping like a baby in a floating cocoon.
In this guide, we’re diving into the best hammock underquilts available right now, what to look for, and how to pick the perfect one for your next adventure.
Overview
If you’ve never used an underquilt before, let’s start with the basics. A hammock underquilt is an insulated layer that hangs beneath your hammock, creating a buffer between you and the cold air. Unlike sleeping pads that can shift around or create pressure points, underquilts wrap underneath your hammock like a sleeping bag from below — no compression, no slipping, just warmth.
Why does this matter? Well, hammocks are breathable. That’s great in summer, but when the temperature drops, that breathable fabric turns into a heat thief. Your back and legs lose warmth fast. Underquilts solve this problem by insulating that area without crushing the insulation material, which keeps you nice and toasty.

What to Look for in a Great Hammock Underquilt
Let’s break it down. Picking the right underquilt isn’t just about grabbing the warmest one. Here’s what you really want to keep in mind when shopping:
Temperature Rating
This is huge. Choose an underquilt rated for about 10°F colder than the coldest temperature you expect. Why? Better safe than sorry — especially when nature throws you a surprise chill.
Insulation Type
You’ve got two main choices: down or synthetic.
- Down is super lightweight, compresses well, and offers top-notch insulation.
- Synthetic is heavier and bulkier but performs better in wet conditions and is more affordable.
If you’re often in damp environments or on a budget, synthetic could be your friend. But if you’re trying to shave ounces off your pack, down is worth the splurge.
Weight and Packability
For backpackers, weight matters — a lot. Look for something under 30 ounces if you’re trekking long distances. Also check how small it packs down. No one wants an underquilt that hogs half the pack.
Length and Fit
Make sure the underquilt fits your hammock and your body. Some are designed for full-body coverage, while others only protect the torso. If you’re taller than average, look for a long version. You’ll thank yourself around 2 a.m.
Ease of Setup
Straps, clips, and shock cords — oh my. A good underquilt should be easy to attach and adjust without needing a manual or a third hand. The simpler the setup, the quicker you can crawl in and crash after a long day.
Durability and Materials
Tough outer shells (usually ripstop nylon) are key. Bonus points for water-resistant treatments or DWR coatings. Nature is wild, after all — twigs, rain, and rough ground happen.

FAQs
Do I really need an underquilt for hammock camping?
If you plan on sleeping in a hammock in temperatures below 70°F, yes. Even in mild temps, the air beneath you can suck away body heat. An underquilt keeps your underside warm — it’s a huge upgrade from sleeping pads that can slip and shift.
Can I use a sleeping pad instead of an underquilt?
You can, and many people do. But pads can be awkward in a hammock and don’t conform as well to your body. Underquilts offer more consistent insulation and are usually more comfortable for side or back sleepers.
What temperature rating should I choose?
Aim for a quilt rated 10°F lower than the lowest temperature you expect. If you’re camping in 40°F weather, go for a 30°F underquilt. You’ll stay warm without overheating.
Are underquilts waterproof?
Not exactly. Most are water-resistant, not fully waterproof. You’ll still want a tarp or rainfly if you expect rain. Some quilts have DWR coatings to repel moisture and dry faster.
Can I use a regular sleeping bag as an underquilt?
Technically, yes — if you’re crafty with suspension. But it’s not ideal. Sleeping bags aren’t designed to hang under a hammock and won’t insulate as effectively. A purpose-built underquilt is far more efficient.
Do underquilts come in standard sizes?
Not always. Some are full-length, some are three-quarter. Be sure to check the length and width, especially if you’re tall or broad-shouldered. Some brands offer custom sizing, which can be a game-changer.
Conclusion
A hammock underquilt might not be the first thing you think about when planning a camping trip, but once you try one, it’s hard to go back. Whether you’re backpacking through the mountains, hanging in a state park, or chilling in your own backyard, the right underquilt can transform your setup from “pretty good” to “can I live here now?”
So take a minute to think about your camping style, your favorite seasons to hang, and your budget. Then pick an underquilt that fits your vibe. There’s something incredibly satisfying about waking up warm, well-rested, and suspended gently between two trees.
