Phoenix Econ 40



Hammock Gear Under Quilts

Frequently Asked Questions

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 Econ 40˚

With premium water resistant, 800 fill duck down, the 40°F Phoenix Econ is rated conservatively. The Phoenix Econ is the 'little brother' of the Incubator Econ, 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 Econ 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 Econ 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 Econ comes complete with a stuff sack, storage sack and everything needed to suspend the UQ from your favorite hammock.

Duck 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 4.5 liters, but due to the nature of duck 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.


Under Quilt Advantages

Chances are you are already aware of the advantages of down under quilts. To summarize: 

  • thermal efficiency
  • weight savings
  • volume savings
  • ease of use & adjustment (especially compared to a pad)
Phoenix Econ 40˚Standard
Fill Weight4.4 oz
Total Weight13.5 oz


We utilize the finest 800 fill power, water-resistant Duck 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 Econ quilts are made of Ion fabric. All Ion fabric is specifically designed nylon taffeta which is manufactured for Hammock Gear. This material is a 20 Denier nylon taffeta with a DWR (durable water resistant) coating, which makes it great fabric for lightweight quilts. Weight is 1.1 oz / yd²


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.

  • best buy yet for my hammock

    by Daniel Gibson – 15th Aug 2018

    Finally conquered CBS, wished I had found this several years ago when I first started hammock camping... great adjustment... simple installation

  • Amazing for the price!!!

    by Mylene – 10th Aug 2018

    I got it a few months ago for my first backpacking trip with a hammock!!! It is super light, packs really small. I wish it was a little bit longer as my feet were outside the quilt and it was the only part getting cold!!! I solved the issue using my rain jacket around my feet and that's it!!! For cold or windy conditions this one won't be enough!!!

  • great option for Alpine summer camping

    by pd – 31st Jul 2018

    It's a great product. Well assembled. Wish it was about six inches wider, or that was an option. I'm 6'3", pretty broad shoulders, and sleep in a wide hammock at a pretty hard angle. Doesn't quite wrap up far enough on the far side away from my head, and primary suspension gives my legs hell. Unless you got that exact use case, it's amazing, and would be five stars.

  • Great summer UQ

    by Mike – 2nd Jul 2018

    Very light & packs small. Just what I needed for summertime camping. My feet did not get cold on my first trip but a simple pad will work fine in colder temps. I used this on my Hennessy which is made thicker than my Warbonnet Eldorado. The Hennessy always sleeps warmer anyway.

  • Phoenix Econ 40

    by Daniel – 27th Apr 2018

    I love this thing. My other underquilt is an econ 20 incubator and as the temps are warming, it sure was nice to drop almost half a pound in weight using my new Phoenix Econ 40. I got it just in time for a trip that unexpectedly fell down into the mid 30's (COLD!) and windy. Once I got the Phoenix dialed in, it was amazing. I got a little chilled when it got to the mid-low 30's, but was surprisingly comfortable considering how far I took it passed 40. I'm super impressed (as always) with Hammock Gear's quality.

  • no chance to use do to weather

    by Unknown – 16th Apr 2018

    Have not used yet that is why 4 Star but five star for construction and customer service should be fine

  • Never Using a Pad Again! This UQ is AWESOME!!

    by G McD – 10th Apr 2018

    Picked the Econ Phoenix 40 up to function as a 3-season UQ. I was tired of wrestling with pads and was taking a bit of a chance on a 3/4 UQ, as I had never used one before. I have an Econ Incubator 20 for winter camping, and it's great, so I figured if I was going to take a chance, I would rather do it with HammockGear, who I already know and trust.

    When it comes to the Econ Phoenix 40, I got way more than I bargained for. It is very light and packs down small enough that I just crammed it into the sack for my top quilt. It all fit in one bag. We were out camping with the scouts this last weekend, planning on nights in the upper 40s/low 50s ... and we got night-time temps in the very low 30s (one night was 31 degrees). I was completely comfortable all night long. I was concerned my feet might get cold without any UQ protection under them, but they didn't. I slept like a champ. I didn't want to get up in the morning.

    Our troop has opened up a hammock option for senior scouts, and I will turn as many of them on to HG as I can. This quilt is great and I am completely confident in it's ability to keep me warm well below its stated comfort range. You may not sleep as warm as I do, but I had no issues at 31 degrees. I don't know that I'd take it any colder than that (that's what my Incubator is for), but I'm confident this UQ will perform in all but the coldest of temps. Very well made. I threw in some Dutchware ridgeline clips just to help keep it in place ... and ended up only using one at the head end. Worked great. Kept warm. Slept great.

    Between Dutch and HG, I just can't imagine needing anyone else for my hammock gear. Great products. Great service. Awesome.

  • Don't be scared of "Econ"

    by Dean – 12th Nov 2017

    Added this to my arsenal a little while ago and love it so far. Handled a chilly night in low 40's on my Chameleon without any troubles and I loved the light weight and easy deployment. Great product!

  • Phoenix Econ 40

    by Max1840 – 14th Aug 2017

    Finally got to test the econ40 over a 2 night excursion to the Wallapalooza and it performed well in 50 degree nights. Last try without it was a cold butted bust.

  • Phoenix Econ 40

    by Black – 27th Jun 2017

    Phoenix Econ 40 is the second Hammock Gear under quilt that I am happy to own. I use it in the warmer weather, (40* to 70*) with my WBBB XLC and Ridge Runner. Great deal! Great quality! Came with cotton storage bag and stuff sack. Highly recommend .

  • Fantastic UQ for the price!

    by Chuck – 30th May 2017

    I picked one of these up for a camping trip in Indiana at the beginning of April. Put the order in on a Friday night and the UQ was made and in the mail Tuesday! Crazy light (this quilt is my first experience with down of any type), and kept me warm. I combined it with my 25 degree synthetic sleeping bag (we were car camping) and easily went below freezing-there was frost on our rainflys when we woke up the first morning. Everyone else froze all night, I was nice and toasty (one group even had a heater in their tent! LOL) This company is making good quality gear, and they've definitely earned my business in the future-I'll be back to buy myself a TQ and buy my oldest kid a quilt set. You guys ROCK! Thanks again!

  • Gear Test Coming Soon

    by EarlyBird – 30th May 2017

    I received my Econ Phoenix 40 little less than a month ago. It arrived last weekend and I can't wait to take it out of the house for an official hang. It is currently hanging in my basement with my Hennessy Leaf. I love it. I love the orange color. Also. I am 5' 6" and when I lie diagonal I have no problems with shoulder to foot coverage. Despite it being a 3/4ths quilt... Anyone around this height could get away with enough coverage. The stitching looks fabulous. Doesn't have a funky smell. I especially love that it includes a sack for storage and a stuff sack for your pack. Awesome. Can't wait to take it to the woods. It will cut down on my FRANKENquilts (Costco homeade quilt) bulk and weight.

  • 52 Degree Night In Western Kentucky!

    by Will-p – 26th May 2017

    Unfortunately, if you are like me then you understand buying any Quilt a few days from the start of summer will be somewhat hard to review. I'm a cold sleeper and on 5-24-17 we had a 52-degree night here in Western Kentucky. I took my new ECON Phoneix 40-degree under quilt out and found the deepest darkest hole in Land Between the Lakes. I wore a T-shirt and my trusted V-pants. I left a huge draft in my top quilt. I tried hard to get cold and nothing I did worked. The easy setup and body contour design made the Phoneix ECON a great choice. More important the baffle system along the gathered ends makes this quilt a top pick for any beginner! I can't give this quilt 5 stars yet. If I could I would give a 4.5-star review at this time for design alone. I will need to write a further review when fall arrives later this year.

  • Phoenix Econ 40 Rocks

    by Jay – 23rd May 2017

    Got my Phoenix Econ 40 just in time for my weekend backpacking tip last weekend. I am very impressed with the quality. With the name Econ, I expected it to be lower quality than my Incubator 0, but I can't tell any difference. I had been using my Incubator and burning up with night time temps around 50 to 60. The temp on my trip last weekend dropped to the low 60 and I was very comfortable. Can't wait until fall to try it out in lower temps.
