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.


Orders placed on or after 9/29/20 will ship in approximately 8 Weeks.

All of our quilts ship with a 24" x 36" Storage Sack and Stuff Sack for backpacking.


About the Premium Incubator

The ULTIMATE underquilt for guaranteed comfort... The Standard length Premium Incubator is long enough to generously cover most hammock campers up to about 6’ 2". With premium quality, water resistant, 850 fill power or 950 fill power goose down, this underquilt will protect you comfortably down to its temperature rating. If you are looking for an underquilt that is hassle free and will allow you to enjoy your hammock all year around, 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 Premium Incubator comes complete with our state of the art shock-cord suspension system, featuring color coded s-biners that help you to easily orient the head and foot end of the underquilt for a quick and effortless set-up. All of our quilts are shipped with a complimentary cotton storage sack, and a nylon stuff sack!

Goose Down

Hammock Gear is committed to providing down products that meet RDS (Responsible Down Standard).  RDS certifies that geese and ducks are treated ethically (no live plucking or force feeding) and the down is traceable back to the source.  Both our Premium and Economy quilts use down that meets the Responsible Down Standard.

    Superior Hammock Add-on

    Posted by TJ on 24th Jun 2020

    I added this to my Henn. Hammock and oh wow, huge difference, all the warmth and no wind. Packs smaller than the bubble pad I was using. No hammock should be without one of these.

    You want one of these quilts!

    Posted by Donnie T. on 20th May 2020

    I have not had a chance to hang with this quilt yet... Grrr COVID... But I ordered this under quilt after seeing the quality and value in the top quilt I ordered last year. My wife who is Puerto Rican was even warm in high teens with the 20-degree top quilt. Of course, I then had to order a 0-degree under quilt for deep winter. The quality is spot on not even a missed stitch and if the rating vs. warm is like my top quilt it will be comfortable even below 0-degrees. Also for those of us gram counters, this is the best value for the weight you can get for insulation.

    0 degree Incubator and Burrow

    Posted by Laura on 5th May 2020

    As a ground dweller I would use a synthetic 0 degree sleeping bag stuffed inside a second identical bag on a cot with a 3 inch foam pad. When I decided to convert to hanging I knew I had to find an exceptionally warm set of quilts. After a long search I found HG. They had the highest down fill I could find and all the best reviews! So I decided to give it a try. I ordered the incubator and burrow with a 0 degree rating and 4 ounces of over fill, for good measure I added the under quilt protector. To my delight they arrived 3 weeks earlier than advertised on the website. The Quality is indeed top notch, even to someone who sews wedding dresses, prom dresses and patchwork quilts. I can see the detail and care that has gone into this wonderful set. And yes they do keep me warm! No small feat.
    Thank you HG team for making hanging a reality for me!

    Worth every penny!

    Posted by The Bandit on 26th Feb 2020

    This is hands-down the finest and most well made piece of gear I have ever had the pleasure of owning. Just incredible craftsmanship. Performs fantastically well, full coverage warmth from head to toe with no drafts. And it looks so good I want to hang it in the living room just to look at it. Pull the trigger on this one.

    Very Nice!

    Posted by Michael P - Dallas on 22nd Jan 2020

    Purchase details: Temperature Rating: 0°F (-17°C), Length: Long (6'2" to 6'7") (187 cm to 200 cm), Fill Power: 850, Overfill: Standard Fill).

    I purchased this product believing I would receive something that was just for me, and that expectation was fulfilled. This is truly a premium product!

    At first I was concerned that the width was not enough, as I have broad shoulders and like to feel encapsulated. However, after taking this out for multiple 20 degree nights I can say with confidence this product performed flawlessly.

    On my next purchase (oh yes), I will probably special request an additional panel on each side for additional comfort (as a luxury, not a necessity).

    Thank you HG!!

    10 degree premium incubator

    Posted by Tate hughes on 11th Jan 2020

    This incubator is awesome!! I have yet to do a 32 or below overnighter in it but I did spend a couple hours on it while it 30 degrees out. I recently used it in a very windy overnighter and it blocked the wind and kept me warm! Compact-able and lightweight!!

    Incubator 20 degree

    Posted by Rob nash on 1st Dec 2019

    Hi, I recently placed an order with hammock gear for a incubator 20 degree under quilt and was amazed at the service I received. It took just over a week from date of order to delivery here in the uk which is dam good service I think. The product itself is also excellent I used it this weekend on a bushcraft skills exchange in a cold damp valley where the sun don’t shine much in the winter and temperatures were down to just above freezing. The quilt is very well made and very light weight and compact, it’s half the weight and pack size of my old down quilt but not quite as warm but that was my fault I should have gone for a 2-3 oz over fill. It’s so quick to set up and pack away once you have set the cord attachments to correct length it just a case of attaching one s- beener to one end of hammock and one to the other and that’s it done. I’m a cold sleeper so when I have some spare cash I will order a 0’ degree quilt for the colder times and then I can use one for summer and one for winter. Excellent product guys thank you

    A+ Warmth, A+ Durability

    Posted by Stephanie Stanton on 29th Nov 2019

    I purchased the Premium Incubator (Outer Shell Color: Black (10D), Inner Shell Color: Glacier Gray (10D), Temperature Rating: 0°F (-17°C), Length: Long (6'2" to 6'7") (187 cm to 200 cm), Fill Power: 950, Overfill: 4 ounces) for winter backpacking and some extended car camping trips. I get super cold, even at home (7 fuzzy blankets and an electric throw year round!), so hammock camping past September was a no-go for me. Plus, my best friend and I have a few backcountry snowshoeing trips planned so I knew I had to be prepared. Let me tell you, it is absolutely the perfect temperature sleep every time I’ve used it. I love the ability to adjust the venting and tweak the pitch of the underquilt so I don’t overheat and can limit airflow in high winds. It has kept me warm (and dry but more on that later) for 8 day late September camping trips (lows in the 40s), on high ridge lines in the smokies in mid October during heavy fog (high winds, lows in the mid 30s), and during absolutely torrential rain (lows in the mid 30s) when my tarp completely failed and the site flooded. I was still warm, toasty, and dry inside even though the outside of the incubator was soaked - I was surprised that the down didn’t just release all of the heat. I was expecting to have to bail into my best friend’s synthetic underquilt with him, but the premium underquilt performed phenomenally.

    I do recommend swapping out the included S-beners and upgrade the stuff sack. The S-beners are plastic and the foot bener broke on me before I even used it - they are color coded though so you know which end is the top and which is the bottom), so I upgraded to two all metal S-beners from the check out line at REI -one orange, one black - which solved ever single complaint I had about the underquilt itself. The stuff sack isn’t waterproof, barely contains the low temp quilt, and when carrying the Premium Incubator and Premium Burrow (also an awesome purchase), they took up 2/3 of my 55L pack. I totally recommend swapping in the Sea-to-Summit Ultra-Sil Compression Dry Sak 14L. It’s easy to get the quilt in and out, it crunches the quilt down to half the size of the included stuff sack, and most importantly, ITS WATERPROOF. Protect that down, babes. The storage sack that also comes with the quilts is roomy and easy to manage, so make sure you take your quilts out of the compression saks and store them appropriately . Obviously, neither one of these are make or break features (who cares about a stuff sack and S-bener?) and even with the added expense of those minor aftermarket upgrades this is an AWESOME buy. I’m actually looking into buying another HammockGear Underquilt with less fill to save a bit of weight in the summer months because I know I’m not going anywhere without this quilt again.
