Incubator Econ 30



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 the 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 Econ, and a 3/4-length under quilt - the Phoenix Econ. They are known by many to be the most effective on the market today. One of the primary reasons is this: the Incubator Econ and Phoenix Econ 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.


Lead time at the moment is approximately 5-6 weeks, from your purchase date, to ship out new made to order quilts

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


About the Incubator Econ 30˚

The ULTIMATE underquilt for guaranteed comfort at a low price... The Standard length Incubator Econ 30° is long enough to generously cover most hammock campers up to about 6’ 1”.  With 800 fill power DWR Treated Grey Duck Down, this underquilt will protect you in temperatures down to 30°. If you are looking for an underquilt that is hassle free and will allow you to enjoy your hammock for more months of the year, you have found it.

The Incubator Econ 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 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 Econ comes complete with our state of the art shock-cord suspension system, storage sack, and a stuff sack.


Compression Size


The Stuff Sack we ship with this quilt is approximately 5.5 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 goose down under quilts. To summarize: 

  • thermal efficiency
  • weight savings
  • volume savings
  • ease of use & adjustment (especially compared to a pad)

We utilize the finest 800 fill power, water-resistant grey duck down on the market in all of our Econ 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.

  • Super warm!

    by Mikey – 20th Sep 2017

    WOW. First time user of an underquilt here and I am super impressed. The first thing I notice after hanging the underquilt and jumping in for a test run..... WARMTH! So impressed by this econ line that the wife and I already ordered more quilts! Top and Bottom for her and a top for me!

  • Toasty Warm

    by Marc – 29th Jun 2017

    Have not taken my Incubator Econ 30 out hiking yet, but I did some back yard camping because I could not wait to give it a test drive. LOVE my underquilt. Toasty warm and the suspension is flexible enough to give me a great temp range. Snug it up for full warmth, or loosen it up to create ventilation in warmer weather. Great craftsmanship on the stitching. Highly recommend.

  • best underquilt yet at a afforable proce

    by Brandon Hannis – 24th May 2017

    I received my underground about a month ago and have had it out quite a few times so far and I've loved it. I definitely recommend this product and Hammock gear does an awesome job!

  • Incubator Econ 30

    by Andrew – 20th May 2017

    New to underquilts but could not be happier with my purchase. I was looking into get an Incubator 30 but with the Econ line I jumped at the chance. I slept outside on a low 30s night with the Econ Burrow 30 with the Incubator Econ 30 and I was warm all night long. Great quality, great customer service. I would recommend this product highly.

    Special shoutout to Sean "Shug" Emery for introducing me to Hammock Gear.

  • very happy with this underquilt

    by Unknown – 16th May 2017

    I was very impressed with this underquilt. The quality is much better than other quilts that I've tried. I've tried this quilt in 35 degrees with a 50 degree bag and was toasty warm. The quilt is very well made, the down was well dispersed, and the suspension system is very intuitive. I wasn't able to afford their regular version, but the economy version is still better than other brands that I've tested. Also, customer service was very easy to work with and very friendly. Very happy with the product aND the company, I will definately be a returning customer!

  • a rare 5 star review

    by Austin – 5th May 2017

    It's not often that I'll give a product 5 stars, but the incubator economic 30 deserves it. I got it in the mail yesterday and took it out to test it. It took me a few minutes to figure out how to hang it, but other than that it was really simple to use. This is the third underquilt that I have purchased and the only one that I have been pleased with. It was extremely warm and very well designed. My favorite part is that the baffles are on the outside of the quilt so that even if the quilt is snug against the hammock, the down still will maintain its loft and insulation value. It's just a really well made product, and I couldn't find any loose stiches, or other issues that I ran into with the other ones that I ordered. I was nervous buying the economy version, but am really pleased with the product. One last comment, because these are hand made it take's several weeks to get the product. I emailed the company to ask them if they could get it to me before a backpacking trip I had in 6 weeks and they were very helpful. In the end the product got to me 2 weeks before the trip. I read some review's that said customer service was poor, but in my experience I'd give them 5 stars as well.

  • First time hammock camping with an underquilt and I couldn't be happier

    by Ricky – 24th Apr 2017

    I recently got into hammock camping, and after my first night out, I realized no amount of blankets/sleeping bags would comfortably allow me to sleep on a hammock. I stumbled upon a forum praising HG's recently-released Econ quilts and snagged an Incubator Econ 30 and a Burrow Econ 40.

    Used them this weekend for the first time and I couldn't be happier. I was skeptical as to the pair keeping me warm with no further insulation so i kept blankets nearby just in case the 40-degree weather was too cold for me.

    nope. Woke up perfectly toasty without breaking a sweat either. I love my purchase! I'll be packing lighter next time i go camping!

  • Great Under Quilt

    by Stacy – 17th Apr 2017

    I purchased one of these quilts the week after they started making them. It's the same high quality you'd expect from any hammock gear product, but at a significant savings. Quilt is warm. I haven't tried it in the 30's yet, but I spent a couple of nights in the 40's with no problems whatsoever. The down stays distributed in the baffles, and it packs down super small. I'd been eyeing these quilts for a long time, so it was a no-brainer to pull the trigger when they announced their econ line. Excellent quilt, and it only weighs a few ounces more than the original. It's so good that I'll probably order a burrow to match in the near future.
