Material Information

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.


Quilt orders placed on or after 6/27/19 have a lead time of approximately 1-2 weeks to ship.  Lead time is subject to change.

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.

    This under quilt is incredibly easy to setup and take down. Easy to adjust.
    The under quilt and top quilt pack down to nothing and are light as a feather.
    The workmanship and quality of service is fantastic as well.
    You cannot go wrong with hammock gear!

    Excellent lightweight underquilt

    Posted by John on 10th Sep 2019

    I've owned this since 2014. It's kept me warm down to one night at -10 deg F (with a winter bag) -- I use it at any temp under 70 deg F. Properly tensioned, it sucks up nice and tight and you don't get drafts. I hang it under a Warbonnet Blackbird. You do have to be a little careful to make sure it's pulled around your feet and shoulder when you sleep on the bias, but it's long enough to do that.

    Premium Incubator 20 degree

    Posted by Fred on 3rd Jul 2019

    I have not used it in the hammock yet as it has been 80 degrees at night where I am from, but the quality is fantastic, and I know it is warm as I have sat with it indoors with my ac at 68 degrees (it was too warm for that temperature for my liking) but I can imagine dropping down to 30 or 20 degrees this will be fantastic.

    Great Quality Product!

    Posted by Tanya on 28th Apr 2019

    I bought this UQ to use underneath my WB XLC. I absolutely LOVE this quilt. It is very well made, has lots of loft, and is easy to attach and angle to my hammock lay. I would definitely recommend this product. I've bought quite a few products from HG and have not been disappointed. They have excellent customer service, prompt shipping, and an easy return process (if needed).

    Awesome Quilt and AMAZING Service!

    Posted by Chuck on 4th Feb 2019

    First of all I want to brag on the service I was provided by HG. I had a pretty tight timeline for a trip I was taking and they went over and above to get it to me... then I had several questions on the fill and thought maybe it was a bit low... this was my first dedicated underquilt and wasn't sure but they asked me to send it back to take a look... and THEY paid for shipping, adding extra fill, and shipping it back to me all VERY quickly. BTW, the bag was correct the first time but they clearly went out of their way to satisfy the customer... and for that I'll be one for life... oh, and the Incubater is FREAKING AWESOME!!!!!!!!! Amazing service and Amazing quality so don't hesitate to get one!

    0 degree Burrow and Incubator

    Posted by MR. T on 22nd Jan 2019

    I just wanted to say how pleased I am with my purchase from Hammock Gear. The whole buying experience from start to finish went without a hitch. From the phone call to customer service to make a change in material, to putting them in to use. I mean top quality all the way. If your thinking of a future purchase and your on the fence, don't be. Everything I've experienced from H.G. has been first rate . Very Pleased.
