Hammock Gear Under Quilts

Product Specs

Frequently Asked Questions

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 12/5/2018 have a lead time of approximately 10 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 Incubator comes complete with our state of the art shock-cord suspension system and a 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.

    Premium incubator under quilt

    Posted by Grant on 13th Nov 2018

    Absolutely worth every penny. This piece of gear is aptly named: incubator. It does just that. It's rated at 0 deg F, but I was warm and comfortable even when temps dipped to -20 F (w/ wind). Not only are their products amazing, but they people at HG are too!

    Camo Incubator 10

    Posted by PMAN (Hike4life) on 23rd May 2018

    I recently purchased the incubator 10. As advertised, it took approximately seven weeks to fill my order. The camouflage material, design, and craftsmanship are second to none. I will have to wait until next winter to use it, but I have no doubt that I’ll be pleased with this purchase.

    Incubator 30

    Posted by Dave H. on 9th Nov 2017

    As with my previous under quilt purchase the quality is top notch. Color is exactly as expected with a great feel to the fabric. Color coded "S" biners make it easy to know which end you're grabbing out of the stuff sack so you can hook up one end without exposing the rest of the quilt to possibly being dropped on the ground. Suspension is easy to figure out and works well to snug the quilt up against the hammock. Looking forward to my next over night trip surrounded by downy goodness!

    I couldn't decide between the 20 and the 40 then this showed up.

    Posted by Alan M on 30th Jul 2017

    For a few months I had been trying to decide on going with the extra weight of the 20 or over stuffing the 40 to get the 3 season temp rating I was looking for. When I was finally ready to buy I came back to the site and found this quilt. The quality is top notch and it fits my Dream Hammock like a glove. This is my second purchase from Hammock Gear and I couldn't be happier with the customer service and workmanship.

    This is my first under quilt. I chose the incubator 40 because of the reviews on this site. I don't have anything to compare it to but I am very please with my choice. The over all quality of the quilt is outstanding. A couple of things stand out for me. One is the suspension. Two is the immediate warmth. It is unbelievable, as soon as you lay down in your hammock you can feel it.

    Outstanding workmanship

    Posted by Jeff Creamer on 14th Mar 2016

    I purchased my Incubator 40 under quilt about a year ago and have waited until I put it through plenty of use to leave a review. First of all, this is my 5th under quilt from various cottage manufacturers. It is without question the best quality. This is primarily due to the suspension set up used by hammock gear. The suspension is so customizable that I think it could be used on just about any hammock. I have a blackbird and this quilt fits it like a glove. While it is rated to 40*, I have been comfortable down just below 40 (37*). I am a cold sleeper and was surprised at the level of warmth. I plan on selling some of my other under quilts and purchasing a 20* soon. Thanks guys for excellent work!

    Top quality underquilt!

    Posted by Steven on 10th Mar 2016

    I haven't had the chance to use it yet. The quality is great. There seems to have been a lot of thought put into this quilt. I will definitely purchase a top quilt from Hammock Gear when I get the money.

    Also military friendly, always a plus!
