Hammocks are great for immersing yourself in nature. Whether you want to take a quick nap during the day or sleep in one overnight, a hammock is versatile and super portable. Some people even love using them as lightweight options for hammock camping.
At A Glance: Our Top Picks for Hammock Underquilt
Summer days are great, but colder climates and seasons are more challenging. Sure, you can get away with wiggling into a sleeping bag in your hammock, but there are better ways to keep warm. Invest in a hammock underquilt and never feel cold in your hammock again.

If you want a reasonably priced option, then this synthetic, polyester-filled hammock-specific underquilt is a worthwhile option. It is rated 40-50F, which is enough for most people sleeping in a hammock! And the shape is designed to be super comfortable as well.
It also packs down into a relatively small drawstring bag, even though it is filled with synthetic insulation. Of course, a down-filled underquilt would be better, but the price is a reasonable alternative.
The weight is also not too bad, at just under 1.5 pounds. So, although it is not the lightest option on the market, it’s reasonable for backpacking. Unless you are doing the John Muir trail that is!
The ENO Vulcan Hammock Underquilt is very similar to the Blaze, except that the Vulcan is made of synthetic material. That’s great for two reasons – it’s slightly cheaper, and it’s easier to dry in case the filling gets wet.
Instead of Blaze’s goose down filling, the Vulcan has PrimaLoft Synergy insulation that is made of both fine- and ultrafine-denier continuous filament fibers. These form tiny air pockets that trap body heat and keep out cold to keep you warm 30 – 40 F (-1 to 5 C).
The cut of this full-length underquilt ensures top insulation with maximum comfort. The inner lining is narrower than the outer shell, making sure that the underquilt hugs and follows the body’s contours.
Due to the materials and filling, this is a bit heavy at 30 oz but still compresses tightly to fit any backpack.
One of the most functional pieces of hammock camping gear you’ll find is the Outdoor Vitalis Aerie Underquilt. It’s a 5-in-1 product that you can use as an underquilt, pod system, technical blanket, a sleeping bag, and a double sleeping bag if you have two of these (you can zip them together). Despite its heavyweight use, the Outdoor Vitalis Aerie is still very light at 27 oz.
This product is the brainchild of the owner’s personal dilemma in finding affordable outdoor gear. The result is the Outdoor Vitalis line of gear that is only sold direct-to-consumer (you won’t find these products in retail stores) to keep it highly affordable given its many uses.
The 20D Ripstop Nylon with their proprietary VitalDry Durable Water Repellent (DWR coating) makes this underquilt tough, durable, and dry. The grid design also follows the shape of your body to keep the cold air from going creeping into tight spots.
It’s quite customizable as it will fit almost any hammock size. It also has a drawstring down the body so you can close it up all the way up to your face. Because of its versatility, it has zippers and straps that you can use to attach blankets and other gear you have.
Outdoor Vitalis claims that its 800-fill-power down keeps you insulated for down to 30 F (-1 C). However, after some test runs, this will keep you warm down to 40 F (5 C).
The simplicity of its design keeps the price tag relatively low, so you can get this very easily. It has a 300T Polyester Pongee Lining for insulation and the standard 20D Ripstop Nylon and Durable Water Repellent. It keeps you warm down to 40 F (5 C), so this three-season underquilt is great for camping, going to the beach, or just hanging in the backyard.
The full-length hammock has a universal fit. It also has a split design at the ends to make sure that it stays in place under your hammock. The quilted design also helps the filling stay put.
Considering the material and filling, the hammock surprisingly weighs 26 oz, which is heavier than some goose-down underquilts.
The bungee cords and suspension kit is not included with the purchase of this product.
A big drawback of this is the quilting. The stitches are arranged in parallel lines across the quilt, which means it doesn’t follow the body’s contour very well. Cold air sometimes slips between the body and the hammock.
Unlike some products, a underquilt will not be ideal 100% of the time. The best hammock underquilts are made for specific seasons and temperatures. It mostly depends on how and when you use it most.
The best value-for-money multi-purpose product is the Outdoor Vitalis Aerie. It’s customizable, can be used in many ways, and does its job in keeping you warm. It’s lightweight for its size and functions and has straps and zippers for other hammock gear.
Many campers still consider the ENO Blaze Hammock Underquilt as the best option. It is sufficiently warm, greatly built, and will last you for years.
Not all underquilts are created equal. The first step of finding the best underquilt is to know the size of your own hammock. While some hammocks will claim a universal fit, it’s still a one-size-fits-most situation.
Most of the time, temperature ratings on the products are not 100% accurate. It will still be close, but don’t count on it 100%. Know where you are going and bring additional gear if necessary. Having a 50 F underquilt doesn’t mean it’s unusable in cold weather; it just means you have to pack extra blankets or warmer clothing.
A great underquilt will not bunch up and allow cold air to creep in, or shift positions and leave you shivering in the night. Take note of the materials used especially in the padding, and pay attention to the product’s water repellent features.
And worst case scenario, you bring your sleeping bag and it can double as a hammock underquilt!
