I’ve had my eye on the ENO Blaze Hammock Underquilt for a while now, and I finally took the plunge. At $275, it’s definitely a luxury hammocking item, not a “must-have” unless you’re planning some serious winter camping. But let me tell you, it’s worth every penny for staying warm and cozy in your hammock during chilly nights.

Warmth and Versatility: This underquilt is a real game-changer. It’s filled with Downtek water-repellent down and rated for temperatures between 30-40°F when used with a compatible top quilt or sleeping bag. But what surprised me is its versatility. You can wrap it around your hammock and yourself, creating a snug sleeping bag-like cocoon for extra warmth. It’s also big enough to fit double hammocks, perfect for couples or those who like a little extra room.

Size and Adjustability: The ENO Blaze Underquilt is larger than I expected, measuring 6’6″ x 4′. This full-length adjustable quilt can be rigged to wrap around you entirely, providing even more warmth. The shock cord suspension system is a breeze to set up. You can quickly attach it under your hammock using the carabiners on the hammock straps. Fine-tuning the fit is easy, and you can make adjustments even from inside the hammock.

Materials and Performance: Made from sustainably sourced Downtek water-repellent down with a ripstop nylon shell and moisture-repelling DWR finish, this underquilt is built to last. During a test run on a chilly 39°F day, I felt perfectly warm in my hammock for 30 minutes, even without a sleeping bag or top quilt. With the right insulation on top, I’m confident this underquilt will keep me comfortable within its temperature range.

Additional Considerations: If you’re concerned about wind or the elements, ENO offers a range of hammock shelter systems and rain tarps to complement your setup. As someone living in Minneapolis, where winter lingers, I’m excited to take this underquilt on hikes and enjoy outdoor activities even during the coldest days.

Storage and Care: The ENO Blaze Underquilt comes with a convenient stuff sack, packing down to the size of a small sleeping bag (7″ x 12″). It also includes a large cotton bag for long-term storage, just like you would with a sleeping bag, to ensure optimal performance and lifespan.

A Memorable Night Under the Stars: I’ll never forget the first night I used the ENO Blaze Underquilt. The temperature had dropped to around 35°F, and I was a bit skeptical about how warm I’d stay. I set up my hammock, attached the underquilt, and crawled inside. To my delight, I felt cozy and snug, almost like I was in my own little cocoon. I gazed up at the stars, feeling the gentle sway of the hammock, and realized that this underquilt had transformed my hammock camping experience. I stayed warm throughout the night, and it was one of the most peaceful sleeps I’ve had outdoors.

In conclusion, the ENO Blaze Hammock Underquilt is a top-notch choice for anyone serious about cold-weather hammock camping. It’s a bit of a splurge, but the comfort and warmth it provides make it a valuable addition to my outdoor gear collection. Plus, knowing I can extend my outdoor adventures even in the heart of winter has me looking forward to chilly days.

Buyer’s Guide to Buying the Best Hammock Underquilt

When choosing the best hammock underquilt for your needs you really have to look at where and when you intend to use it. If you’re a fairweather hammock camper in the summer and spring you won’t need nearly as much insulation as a deep woods winter hiker.

Price is always going to go up as quality and especially lightweight features do.

Make sure and keep in mind just how much underquilt you really need for your climate and camping needs.


As with sleeping bags there’s a broad range of prices you can pay for a hammock underquilt. They start around $40 to $50 and can go as high as several hundred for high end products from famous brands.

You can get a really good hammock quilt made from solid materials for around $100 to $150 no problem.

Temperature Rating

The temperature rating of an underquilt gives you a range of temps that your underquilt will work well in. The higher number tells you the comfortable sleeping temp while the lower one gives you a lower limit.

This is the same system used when comparing different sleeping bags. Some underquilts will actually list a male and female set of numbers as men and women generally run at different temperatures.

One important caveat to underquilt temperature ratings is that they only work when combined with a suitable top cover or sleeping bag.

Insulating Material

When it comes to insulating material within your underquilt there are two major types with a huge number of different specialty and proprietary subcategories.

Down – Down insulation is made using the plumage and feathers of geese and ducks. Goose down is the lightest and most insulative but duck down still does a good job for a lower price.

Down has the highest r-value by weight of any current insulative material, though synthetics are getting close. One thing to keep in mind is that down quickly absorbs water and loses its insulative properties when wet.

If you’ll frequently be camping in wet conditions you should keep this in mind. When comparing different down underquilts you should look at down fill and down weight.

Fill tells you how many cubic inches of loft a single ounce of down has. The higher the number the greater the insulative properties of the down.

Synthetic – Synthetic down is usually made using polyester and is designed to replicate the qualities of natural down without the downsides. It retains its warming properties when wet and is a little bit cheaper on average.

The downside to synthetic down is its weight. Even the best synthetic downs have less insulating abilities on an ounce for ounce basis than down.

Length and Shape

Underquilts come in a variety of sizes and shapes. Some are basically just rectangular blankets with attachment points to connect to your hammock.

Others are designed to conform closely to your body, with a few even able to close up like a sleeping bag around you. Size wise you should look for one that comfortably covers your entire body with at least 6 inches to spare.

Most underquilts will be at least 6’ long. Some of the larger ones are as long as 7’6” or even 8’.


Like most outdoor insulating items underquilts have been dropping in weight as materials advance. The vast majority will weigh from 1 lb up to about 4 lbs. This is affected by the quality of materials as well as how large and insulative it is.

A lightweight summer quilt is naturally going to weigh less than a 4-season on designed for cold weather hammocking. If you’re willing to spend a premium you can get sub 1 lb underquilts that are rated for cold weather camping.

Water Repellency

If you’re taking your underquilt out in damp or very humid conditions you need to have at least basic water repellency coatings. These help prevent water from infiltrating your underquilt and soaking the fill.

This is especially important with down underquilts as you’ll lose your insulation if it gets wet. Synthetics will still keep you warm but they can rapidly increase in weight until they’re uncomfortable to carry.

No matter what coating you get make sure you understand their limitations. Even the very best aren’t waterproof. If they get caught in the rain for any length of time they’ll rapidly soak through.


Most underquilts have about the same overall construction. They’re made from lightweight nylon or polyester with baffle construction to keep the fill from shifting too much.

Things that can help improve overall durability include:

  • Rip-stop Nylon
  • Double Stitched Seams
  • Reinforced Attachment Points

As long as you catch any rips or tears early on it’s easy to patch them up. The biggest thing you have to worry about is a major rip or the loss of fill.

3-season or 4-season rating

There’s no hard and fast system for 4-season underquilts. Generally speaking these have a temperature rating of at least 10 °F and are designed with winter camping in mind. For the other 3 seasons of the year they have a venting system for warmer conditions.

3-season underquilts usually go down to about 20 °F or 30 °F but lack the ability to vent. It’s important to keep your own needs in mind when considering different underquilts.

A 4-season hammock underquilt is definitely going to be too warm and heavy for summer camping. Depending on where you are in the world it may be too warm for late spring or early fall as well.

Consider whether you want a single do it all underquilt or would prefer to buy two or more for different seasons. You’ll spend more to be sure, but you won’t have to haul around a heavyweight winter underquilt when it’s 70 °F at night.

What is a hammock underquilt?

A hammock underquilt is a specialized insulation layer designed to keep you warm and comfortable while hammock camping. It attaches to the underside of your hammock, providing insulation and preventing heat loss to the surrounding air.

Why do I need a hammock underquilt?

When you sleep in a hammock, your body is exposed to the cold air beneath you, which can result in discomfort and even hypothermia in colder temperatures. A hammock underquilt acts as a barrier, keeping you warm and ensuring a restful night’s sleep.

How does a hammock underquilt work?

A hammock underquilt works by trapping warm air between its layers and your hammock, creating an insulating barrier. It effectively blocks cold air from entering the hammock and keeps your body heat from escaping, providing warmth and comfort.

Can I use a sleeping bag instead of a hammock underquilt?

While it’s possible to use a sleeping bag inside a hammock, it may not provide optimal insulation or comfort. Sleeping bags compress under your body weight, reducing their insulation value. Hammock underquilts are specifically designed to fit the contours of a hammock and provide efficient insulation without compression.

Are hammock underquilts suitable for all hammocks?

Most hammock underquilts are designed to be compatible with a wide range of hammocks. However, it’s essential to check the specifications and dimensions of the underquilt to ensure it will fit your specific hammock properly.

How do I attach a hammock underquilt to my hammock?

Hammock underquilts typically come with suspension systems or attachment points that allow you to secure them to your hammock. These attachment points can be carabiners, hooks, or shock cords. Follow the manufacturer’s instructions or refer to the user manual to properly attach the underquilt.

Can I use a hammock underquilt in warm weather?

Hammock underquilts are primarily designed for colder temperatures to provide insulation. In warm weather, using an underquilt may cause you to overheat. It’s best to use a hammock underquilt when camping in temperatures below 70°F (21°C) or in areas with unpredictable weather conditions.

How do I clean and maintain a hammock underquilt?

Cleaning and maintenance instructions can vary depending on the materials used in the underquilt. Generally, it’s best to follow the manufacturer’s recommendations. Most underquilts can be hand-washed using a mild detergent, and some are machine-washable on a gentle cycle. Always allow the underquilt to air dry completely before storing it.

Can I use a hammock underquilt for other outdoor activities?

Hammock underquilts are primarily designed for hammock camping but can also be used for other outdoor activities that involve sleeping in a suspended hammock, such as backpacking and hiking trips. However, they may not be suitable for ground-based camping or activities where a hammock is not involved.

Remember, it’s important to thoroughly research and choose the right hammock underquilt based on your specific needs, preferences, and the weather conditions you’ll be camping in.

Best Hammock Underquilts Recap

Final Thoughts

Well there you have it.

Picking the best hammock underquilt depends heavily on what you’re willing to spend and how you intend to use it.

A winter weight underquilt is probably going to be too much insulation for a summer hiker and a lightweight down one might be too expensive.

Compare your average camping trip to the capabilities of each quilt to find the perfect one for your needs.
