Hammock Gear Under Quilts
Goose down under quilts have proven to be, without question, the preferred choice for insulating the underside of the hammock. Due to super light weight, compressibility and versatility, they outshine the alternatives by a landslide. Their thermal efficiency has allowed brave campers to push the boundaries of cold weather hammocking. Virtually every hammock camper has experienced - through his or her learning curve, the dreaded CBS, or "Cold Butt Syndrome". And virtually every owner of an under quilt has effectively learned how to avoid it. Once you have experienced a down under quilt, you will "never go back".
Hammock Gear provides a full-length under quilt - the Incubator, and a 3/4-length under quilt - the Phoenix. They are known by many to be the most effective on the market today. One of the primary reasons is this: the Incubator and Phoenix are the only commercial under quilts designed with a contour which mimics the shape a person makes when they are laying in a hammock. One of the added benefits of this construction technique is that it leaves a "flap" of fabric along the top and bottom of every down filled chamber. This extra fabric acts as a "floating baffle" which stabilizes the down and helps prevent its shifting. Another reason our UQ's are popular is this: they contain the ideal amount of down Stability - the down stays put when it should, but the design allows for enough manual shifting of down when necessary.
About the Incubator 40˚
The ULTIMATE underquilt for guaranteed comfort... The Standard length Incubator 40° is long enough to generously cover most hammock campers up to about 6’ 2”. With premium quality, 850 fill power Hungarian goose down, this underquilt will protect you in temperatures down to 40°! If you are looking for an underquilt that is light weight, hassle free and will allow you to enjoy your hammock on the chilly late spring/early fall nights, you have found it.
The Incubator comes with 9 anatomically contoured, differential cut baffles that run the length of the quilt. One of the things this construction technique does is to greatly reduce the shifting of goose down that is sometimes more noticeable in quilts made with premium goose down. This is one of the reasons Hammock Gear quilts are always 15-20% overstuffed. The differential cut, contoured baffles also provide the highest level of fit which is critical to keeping warm. The Incubator comes complete with our state of the art shock-cord suspension system, Nite-ize #2 plastic "S" biners, and a stuff sack.
Under Quilt Advantages
Chances are you are already aware of the advantages of goose down under quilts. To summarize:
|Fill Weight||6.6 oz||7.0 oz||7.4 oz|
|Total Weight||16.4 oz||16.8 oz||17.2 oz|
We utilize the finest 850 fill power, water-resistant goose down on the market in all of our quilts. It is tested and certified by the International Down and Feather Testing Laboratory.
All Hammock Gear quilts are made of ARGON fabric. All ARGON fabric is specifically designed ripstop nylon which is manufactured for Hammock Gear. We offer both 10 and 15 denier weights with certain colors only available in one or the other. ARGON 67 (10d) weighs 0.67oz/square yard while ARGON 90 (15d) weighs 0.90 oz/square yard. It has a Durable Water Resistant (DWR) finish. The DWR not only improves the water resistance of ARGON , it also enhances the fabric by improving overall strength, tightening the weave and thus increasing its down-proofness. Calendaring of the fabric further enhances the down-proofness of the quilt.
All of our under quilts make use of baffle (also known as "box baffle") construction. This means that the seams between the down-filled chambers are not sewn through, but instead consist of a fabric wall about .75 to 3 inches tall, depending on the model.
At Hammock Gear, we use temperature ratings which are very conservative. Compare them in the marketplace and you will agree. Here is a point we wish to emphasize: the first and most important step you must take when choosing an under quilt by temperature is to Know Thyself. Are you a Cold sleeper, a Warm sleeper, or maybe a Really Warm sleeper? Factor this into your selection process and you will be much better off. With under quilts, the more you experiment, the more you will dial this in.

What a quality product at an outstanding price. I wanted to wait until I had actually used this underquilt in the field before I gave my opinion and I wasn't disappointed. Super lightweight and it keep in nice and warm in the North GA mountains. I love it!

I decided to order a HG under quilt based on some reviews and research over at hammock-forum.net and I have to say, this is one fine product. So much so, that I've decided my next purchase will be one of their cuben fiber tarps. The quilt exudes craftsmanship and quality. You can tell that someone who cares about their product and reputation crafted this quilt. I just got through using it on a section hike of the AT and woke up the first morning to 22 degree weather and was quite comfortable. I got the 40 degree quilt with 2 oz. of overstuff and am very pleased with my decision. I highly recommend Hammock Gear as well as this quilt!!

Very fine construction ; lofty and light! Haven't had a chance to use it yet but will write back when I do. Looks like the 40* Incubator will fulfill my needs! Thanks Adam & Jenny!

I ordered the incubator 40. I live in FLA and usually go backpacking and camping in the summer months out west and hammock camping in the winter months in the SE. Did not need much more than the 40. Build quality is excellent. I have a Western Mountaineering sleeping bag that I use when I go tent camping out west. I liked the under quilt so much that I ordered a Borrow 40 to use when hammock camping and in lew of my sleeping bag when I am tent camping to save some weight and room in my backpack. Enjoy!

Great contour, ease of use and insulation make this quilt a no brainer.

I purchased the Incubator 40 with 2 extra ounces of down to make a 30 degree Underquilt. I spoke with Adam who advised he would also increase the thickness to allow for the added down. The quality of everything about the quilts is amazing. It fits my Hennessy Explorer Deluxe perfectly. It is very easy to attach and adjust and the warmth is felt just moments after laying in your hammock. I asked my wife to get in the hammock while I adjusted the Underquilt (outside temp was about 40 degrees) and after about 2 or 3 minutes, I unhooked one end of the Underquilt without her knowledge, and she felt the chill immediately. I ordered the outside in camo, with olive green on the inside and it looks great. It is very light, compresses very well, and is incredibly warm. I also purchased the Burrow Top Quilt in the same specs and was equally impressed. I am perfectly warm in my hammock with the Underquilt and Top Quilt @ 40 degrees outside temp. In the same hammock at 52 degrees with a 30 degree sleeping bag, a under pad, and a ponch liner, I was much miserable. A Top Quilt and Underquilt are by far a better solution, and after checking many places, Hammock Gear is the best.

I knew this underquilt was going to be awesome, but it went beyond my expectations! Not only does it block the elements, but you can feel the warmth form the quilt just by lying down in it. Also, the system for hanging this under your hammock is very straight-forward and easy to get setup snugly with your hammock. This makes a huge difference for using my hammock in cold weather, a great purchase.
by Shannon Brooks – 9th Oct 2014
I've been using the Incubator 40 since early 2014 and after my first season I have to say it's a great UQ! I was really surprised when it game already setup with Dutchware and have to say it's been fantastic. The alternate color clips really make it easy to know which end is which.
I've had this UQ down to 30°F and it's worked well. I am a warm sleeper and wore extra layers, but the quilt did the heavy lifting and I was very happy with it's performance!
by Swash – 4th Oct 2014
I rarely give high ratings on anything. I have high expectations for ALL my gear. That said, I was very pleased with this UQ. I've had this out several times and it did just what it said. I'm 5'10" 170lbs (178cm 77kg). The short covered me nearly head to toe and to almost 40 degrees on the mark. Never have I had anything so closely rated in temperature. At around 38f (3.3c) I started to get a very slight chill. At 35f (1.6c) I was starting to get cold enough to disrupt sleep.
This is light and surprisingly tough for how thin it feels.
Unbelievably soft and compacts small.
Very accurate temp rating. Love the end baffles that work like gaskets to keep the warm in.
The Cons (hardly mentionable):
The static suspension lines were a little too long for my hammock to be helpful, it mostly rode on the adjustable suspension while the static suspension laid slack. A little extra tweaking and it was no problem.
When I first got it, it smelled like chemicals or something. Took a couple weeks to air that out completely. Now it's perfectly fine.
Overall I'm absolutely impressed. High build quality, super soft, light, and warm. From now on I refuse to use anything less than HG for quilts.

Suffering from cold-butt/shoulders for my last few trips, I decided to pick up the 40 with 1 ounce of overstuff. I was very skeptical when I received it, as it was about the 1/3 of the size and weight of my current sleeping bag and was rated to the same temperature.
First night I tried it, it went down to about 35 degrees and I was quite warm with just a blanket and some clothes. No more cold patches on my back. You can feel the heat radiating off of it.
If you love camping with hammocks, this is a no brainer.
by Rob Main – 14th Aug 2014
I am a regular return customer. I own an incubator 40 with 2 ounce over, a Burrow 20 and am now just ordering a couple of incubator 20s for the coldest stuff Australia/NZ can throw at us. I love my hammockgear kit and so does every one I recommend them to. Keep up the good work guys!
by Brian – 9th Aug 2014
The temperature rating is spot on and the quality is phenomenal. Get serious folks, this is a niche item that you are not going to walk into REI and pick up. Absolutely worth the price IMHO. I use my hammock in most of south TX and occasionally MN and WI. I originally bought the incubator 20 with an ounce of overstuff to cover all my bases. Like most of us have done with sleeping bags, you end up with overkill your first time purchasing. The 40 is the one that will take care of you 90% of the time without any overstuff. One of the great things about hammocks is interchangeable parts. It doesn't matter which brand hammock you have. I own a Hennessy Asym, a Clark TX150, and a WBBB XLC. Simply outstanding on all makes/models! I bought the "short" version and it gives me complete coverage for my 5' 8" height. It is something to consider if you want to shave a few grams off. With the stuffsack the short 40 weighs 440 grams. It almost doesn't matter though. You are not going to get this level of comfort with a pad!

Great UQ. Can't wait to try it out.
by Kyle - Oregon – 4th Jun 2014
Just got my incubator 40 quilt and took it out for its first trip this past weekend. It's still a little chilly up where I was at and this thing performed flawlessly. It was a breeze to set up and adjust and made my hammock exponentially more comfortable than the crappy sleeping pad I used to have to use. Overnight temps were right around 40 degrees and I had no issues staying warm.
On top of all that, the Hammock Gear service is unparalleled. I knew their products are a handcrafted so I ordered well ahead of my trip, but got a little nervous when I hadn't gotten it a week prior. It took one email and they assured it would to me in time and even expedited shipping on their own dime to make sure of it. I could not be happier with my experience and I will be a repeat customer and recommend Hammock Gear to anyone I talk to.
Thanks for exceeding my expectations!

I ordered the 40F incubator short with extra oz overfill. It has worked very well. It has kept me warm in 35F with high winds. It also has been able to take heavy fog and huge thunderstorms and still dry out nicely. I have been backpacking for over twenty five years and converted to a hammock about 4 years ago. Ive been using a pad but decided for the upgrade. My base weight including poles is under 12 lbs without food and water and I am very comfortable to about freezing. Thanks for a wonderful product.

I am very pleased with my new Hammock Gear 40 down underquilt. Out of the box it was extremely light weight and well made. I was surprised at how light it was! My first field test went well. We camped in wet weather (East TN climate) in the spring. It was about 38 the first night and low 40's the second night. I didn't have a cold spot anywhere on the hammock! I was a little worried because I had never used an underquilt, and this one looked "small" (my buddy was using his eno underquilt and that thing looked massive next to the hammock gear set up). It ended up working perfectly! I ordered standard length and I'm 6' 2". It was all the coverage I needed and nothing that I didn't need. I even slept at a slight diagonal in the hammock the second night and still had no problems. The down stayed dry even though it drizzled multiple times throughout the weekend. I loved the ready-to-go S-hooks that were included. I also liked how they are different colors so you know which direction you're hanging it (I did hang mine quickly in the dark with just a headlamp).
If it helps you to know what other gear I was using:
Eno double nest hammock
Eno dry fly rain fly
I used a Marmot 20 degree mummy bag and just unzipped it and laid it on top of me quilt style.
In the past I have used sleeping pads (from Walmart) to keep my under side warm. I usually would wake up 4-5 times a night due to cold spots forming if I moved. This time I woke up only once each night, but it was just nature calling.
I plan to use the quilt all spring and early summer with no top cover except a fleece jacket. If it gets warmer at night I can just lower the quilt away from the hammock and let a little air in.
By the way, didn't have to do this but thought of it while getting the underquilt out on this trip: If you needed a little warmth during the morning or at night - you could totally use the quilt. It's sized well enough that it would not drag the ground. It would wrap around your upper body nicely. So if you were thinking of getting a down jacket or layer - you could try using this under your coat or just by itself. Sorry so long, but I know I was in need of reviews when I was shopping. I became convinced HG was the way to go after visiting YouTube and the HG site.
Thanks guys! You have an excellent product!

Extremley impressed with the quality and craftsmanship of the work on this quilt,the stitching and weight is awesome. The fabric and overall look of this quilt goes above and beyond what was expected. Will be ordering a top quilt soon my decision was made rather easily after seeing my under quilt. Five stars for overall satisfaction. Love it
by Ryan M. – 22nd May 2014
I called last minute to order the Incubator 40 for an early spring trip to the Boundary Waters and asked if they could build it with short notice. Adam was grateful enough to complete my underquilt and ship it to me before my trip. Great Customer Service!
The quality of the underquilt is great. Sewing quality looks great, and the material looks like it will last. It even came with a convenient stuff sack. The quilt is easily adjustable and has several d-rings to attach to. The quilt kept me plenty warm in 30 degree weather (I ordered 1 ounce overfill). I would highly recommend this quilt to my friends.
by Red Cinema – 22nd May 2014
Ordered an Incubator 40 with two oz extra (aiming at a "30" as per research). Arrived in three weeks. No extra communication came back but the UQ is SWEET (as was the other HG item I owned, purchased used). Sewing is spot-on, everywhere, all the little details are just right. I love the color but suggest future buyers for whom exact color is important check/inquire on exact color, the exact hue came as a bit of a surprise. A good one, as it turns out. HG deserves their stellar rep in the biz.

Didn't get to got on a trip yet. But I did set it up in 30° Weather and took 3 hour nap. Didn't feel cold at all. No cold spots. Very light weight. Very compact.
by Dave – 22nd Mar 2014
Also with a Blackbird, I've used a Thermarest pad for 4 years. I live just North of New Orleans, so the coldest I've slept in the hammock was in the mid 20's. I ordered the 40 with an extra ounce as I typically sleep cold, and most of my camping won't be that brutal. Procrastinating 'til the last minute for an upcoming trip, I emailed Adam with a request to have the Incubator shipped within 4 days. No problem. Ordered Monday, had it in hand on Friday. Backpacking Saturday, the first weekend of March. First night in the 60's was quite comfy and almost too warm, second night got down to low 30's. Quilt worked great, lightened my pack, and a better night's sleep, just what I wanted. Thanks again for the great product and customer service.
by Phillip – 21st Nov 2013
WOW! Ordered on 14 Nov, at the door on 20 Nov. Another well crafted product from HG. I can't wait to put it to use. Thank you Adam, for the time you spent on the phone with me.
by Jerry – 30th Oct 2013
I ordered mine to be made as a 30° .Its Coyote brown M50 on the outside with white argon inside. I have used it so far down to 28° I added a couple of clips to kill side drafts it might be from my lay.
It really is a work of art , warn and light. One of my favorite pieces of gear. I plan on using this for spring and fall. Adam is a pleasure to work with.
by bob wozniak – 7th Aug 2013
Adam, I can't thank you enough for the quick delivery of 2 incubator 40's, your customer service is awesome. Equally impressive is the product, quality and functionality. I look forward to ordering more things from Hammock Gear
by Megan – 3rd Jul 2013
Used this in The Whites in NH and could not be happier. It stuffs down to be very compact. I got a shorter version since I'm only 5'5" and am well covered. I like the different color hooks to remind me which end is which.
by Skygzr – 18th Jun 2013
Getting older I am always looking to reduce my backpack weight so I can go further and do more. I had always used 3/4 underquilts including those from HG, but I could never get the orientation just right. I thought I would have to just continue to compromise, but I ordered a 40 degree incubator from HG out of M50 and now I have the best of both worlds. Lightweight and full coverage. Top if off with great customer service and it makes for an unbeatable combination.
by Lee W. Oklahoma – 28th Apr 2013
The 40* incubator is in my opinion a nearly perfect all season quilt. It has been my experience that the actual comfort rating is more like 25* or 30*. But I also use this quilt in warmer weather as well . All spring and into summer, then early fall/winter. 80* is the cutoff point for me unless its very windy. This quilt is a must for anyone who hangs year round and likes to do so in comfort. It's build very well and requires little adjusting. Doesn't sag late into the night, like some other brands, and will probably last my lifetime. You won't regret it...
by Brandon – 27th Mar 2013
The incubator weighs virtually nothing. It packs up nicely and doesn't take long at all to decompress after unpacking. The 78"length ensures that your entire body is covered and warm. It attaches easily to my suspension. I love all of the extra d rings that were added to the sides, so that you can modify it to work in any situation. I would definitely recommend the incubator to all of my hanging buddies! An overall outstanding product!
by Jim in PA 3/22/13 – 22nd Mar 2013
Heard nothing but good comments and reviews about Hammockgear, it made my decision to buy my first underquilt easy. The hard part was which to get! I decided on the 40° incubator since most of my camping is around the summer months. I did get 1 oz. overstuff just for a little added warmth, I had already placed my order when I decided on the overstuff so I emailed them and they changed my order no problem! The great customer service and the quality craftsmanship should make Hammockgear an easy choice for anyone!
by WD – 12th Feb 2013
After a year of cold-butt in my Blackbird, and multiple failures of pads and home-made underquilts, I bit the bullet and purchased this Incubator 40. It fits great, is easy to adjust, and the anatomical shape is perfect - it really fits like a glove. I'm glad I got the full length (no more messing around with a separate pad for my feet that can shift) instead of the 3/4. I've slept a couple of nights that got down into the low 60's, and felt no cold spots. If you have a hammock, do not hesitate to purchase the HG Incubator. It oozes craftsmanship, performs as claimed, and is a great value.
