Hammock Gear Under Quilts

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 8/16/2018 have a lead time of approximately 4 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 Phoenix 0˚

With premium water resistant, 850 fill goose down, the 0°F Phoenix is rated conservatively. The Phoenix is the 'little brother' of the Incubator, approximately 3/4 length. It's ideal for people who are pack size and weight conscious and want to shave those few extra ounces without sacrificing much in warmth or comfort. The Phoenix helps you maximize every ounce by using goose down and with 9 differential baffles that run the length of the quilt, which helps keep the down from shifting, providing more warmth. (The baffles make this much warmer than similar quilts using "sewn-through" construction, allowing more loft).

The Phoenix has a three dimensional, ergonomically shaped cut, which not only reduces weight, but provides a more secure wrap around the hammock, eliminating drafts. This underquilt (or UQ) is 3/4-length. This means it is designed to insulate you from your shoulders down to below your knees. Many hammoock campers will use a small piece of closed-cell-foam pad under their lower legs and feet since they typically require less insulation underneath to stay warm. The Phoenix comes complete with a stuff sack and everything needed to suspend the UQ from your favorite hammock.


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. For more information visit: http://responsibledown.org/


Compression Size

The Stuff Sack we ship with this quilt is approximately 5.5 liters, but due to the nature of goose down, it can be compressed further with an aftermarket compression stuff sack.  We do not recommend keeping the quilt compressed for more than 24 hours.  The quilt should be stored in the cotton storage bag provided, when not in use.

Total Weight20.13 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.


Temperature Ratings

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.

  • Total Game Changer

    by DDVW – 23rd Jul 2018

    I’ve been using a variety of Hammocks over the years- ENO, Hammock Bliss, and of course Hennessy (the best). I was always annoyed by the complication and inefficiency of using a z-lite (or Hennessy) sleeping pad in my hammock, although the ENO with a pocket for the pad worked a little better.

    So, this past week I went to Camp Rock Enon with a cheap Chinese made Hammock, and woke to that familiar chill beneath me around 3am.

    I retrieved my under-quilt from its stuff-sack (lighter and more compact than pad I’ve ever tried), clipped it on, and DING! Like magic (instantly) the chill beneath me was gone. I spent the remainder of the nights totally comfortable with just a Thermorest blanket in the hammock with me.

    These were 50 degree nights, but I have little doubt this under quilt is the final solution to the bottom chill. It’s pricy, but it is SO worth every penny!

  • I wish I had known..............

    by DC Bray – 3rd Dec 2017

    I have for years used another popular hammock underquilt made by the same company that makes hammocks. I LOVE those hammocks but I had a problem with their underquilt always slipping to one side in the middle of the night. Freezing, I'd get up several times in the night to adjust the UQ. Then I switched to Hammock Gear. WHAT RELIEF! The extra few inches of width, the adjustable collar, and the awesome suspension system ended the UQ slippage during the night!!! The quality of the fabric and baffles were even more wind-proof for the underside. I stay so roasty-toasty warm that I don't have to carry as much night layers of clothes so I've lightened my pack, too! Also, being able to personalize your gear with color choices makes identifying each other's gear easier when packing for the family. I'm now replacing all my past UQs with Hammock Gear UQs!

  • Quality and Value

    by Claudia Wilson/Slack Packhiker/Lucy on the trail – 14th Mar 2017

    HG offers high quality and gear that is value priced. The construction of my 0 degree Phoenix is flawless. It's a combo of beauty and function. Puffy down snugged up against the hammock promises and delivers warmth and comfort.

    Additionally, HG is completely tuned into customer satisfaction on all fronts. They do take care of business, earnestly.

    Love these guys and their quilts

  • Jacks R Better but Hammock Gear is Best!

    by Cheesewhiz! – 30th Sep 2015

    Have not taken my new piece of gear out on the trail yet but from looks alone this piece is impeccable! I have the Jacks R Better no sniveler, old rag and nest for when I used to have a Hennessey. Thie quality of this under quilt was obviously very meticulously thought out. Thank You!!

  • great under quilt

    by henry Thomas – 1st Apr 2015

    I have and own several hammock gear quilts, it is the only quilt I buy ( I have 5 at this time). I not only hammock camp but ground dwell as well.

  • Quality Product

    by Kelly Kalb – 24th Oct 2014

    This product (and this company) came highly recommended by some experienced campers/scout leaders. The product and my experience met that expectation. Good contact while making the decision and a great product. I used this in (zero degree quilt) overnight in 30 degree weather with wind, and once I learned the best settings I was toasty warm all night with a 40 degree bag over me (unzipped). Now I am actually looking forward to the AT hike in November even more because I know I'll be comfortable all night.

  • Incredible performance

    by Will F. – 26th Feb 2014

    I've been using this 0 degree quilt all winter, but a couple of weekends ago it got a real test. While in the Hammersley Wild area of PA, temperature dipped below zero, hitting -5 one night and right around 0 the next night. With my +10 sleeping bag, I was completely toasty. I've never used any padding for my lower legs, but this time I was glad I brought a small foam pad to ward off the leg chill. I was totally comfortable! Thank for making such a great product. I love hammocking through the winter. So much better than rolling around in the snow.

  • Can't believe i'm first to review this 0Deg Beaut!

    by BrockLeigh – 9th Oct 2013

    I used the 0deg all last winter up until mid January with an old 35deg mummy bag. My lowest recorded temps were in the low 20's and until I climbed out of this UQ I would have though I was at home in my living room. Laying down in this quit is like having someone turn on the heat in your hammock. I have also used this UQ as high as the 60's with a light blanket with success. A true beauty.

    When my money is right I will easily hand it over to Adam and Jen for the convenience and weight savings for one of their TQ's. Without hesitation.

    Love it.
