Incubator Econ 20



Hammock Gear Under Quilts

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.


All quilts are made to order.  Please inquire with for current lead times.

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


About the Incubator Econ 20˚

The ULTIMATE underquilt for guaranteed comfort at a low price... The Standard length Incubator Econ 20° 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 20°. 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 goose down that is sometimes more noticeable in quilts made with premium 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.


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)
Incubator Econ 20˚ShortStandardLong
Fill Weight12.1 oz13.2 oz14.3 oz
Total Weight23.75 oz25.75 oz27.75 oz


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.

  • great!!

    Bought this for my son to use on our 4 day trip to Frontenac Provincial Park this past weekend. The incubator econ performed perfectly..keep up the great work hammock gear

  • Highest reccomendation

    by Tyler – 23rd Apr 2017

    The quality of the Incubator Econ 20 is fantastic. So often the biggest barrier to quality sleep in a hammock is the price. A sleeping pad or cold butt is cheaper than all of the down underquilts previously available.

    With the incubator Econ 20, I had the warmest and most comfortable hammock sleep on a recent overnighter. Temperatures in the Sierra Nevadas temperatures were right around 25 F and this kept me nice and warm.

    Will be purchasing additional products from the Econ line. Thank you for crafting such a high-quality and affordable product.

    by todd – 19th Apr 2017

    Very nice craftsmanship. Havent used it yet over night but hanging in backyard it instantly feels warm. Very quick to arrive and looking forward to using it in a couple of weeks. Will order another for my son very soon.

  • Very Warm! Great Quality! Great Price!

    by Bryan – 19th Apr 2017

    We purchased 2 of these and are VERY impressed at the Quality and Warmth! Hammock Gear even shipped them faster than expected in time for our recent trip! My wife is a cold sleeper and she could not get over how warm she was with this and the Econ 20 Burrow. It was in the low 20's with a good bit of wind. Thank you Hammock Gear for a Great Product and Fantastic Customer Service! We will be purchasing 2 more shortly for our children

  • Simply Amazing

    by Ryan Nichols – 13th Apr 2017

    A++++ Underquilt is beautifully made and performs better than an expected. I would recommend to anyone getting into hammock camping. It's a MUST HAVE!!

  • Finally an affordable high end underquilt!

    by Matt – 7th Apr 2017

    I'm thrilled with this quilt. The weight, the versatility, adjustability, look, value, and WARMTH. Coming from a PLUQ, I am a changed man. I will be buying a matching top quilt for sure. I have slept in it every night since I got it a week ago. I can't get enough! Do yourself a favor and stop thinking about it, just buy it!

  • Very Nice!!

    by Rick – 3rd Apr 2017

    My Econ Incubator was delivered very quickly and I am really impressed with the build quality for something labeled "econ". Haven't had a chance to get it outside yet but I have no hesitation that it will be everything I expected in an a 20-deg under-quilt. Nice job Hammock Gear!

  • Best Buy of the Year!

    by Janet – 3rd Apr 2017

    Where on earth can you get a full-sized under quilt rated at 20 degrees, baffled, filled with down, and made in the USA at this price? Hammock Gear, that's where! I couldn't be more pleased and excited for this line of quilts offered here. The Econ 20 Incubator has such great quality and feel to it. The first night I slept in it, it was instant heat as soon as I laid in my hammock. If you are trying to decide which quilts to get for your hammock, don't wait too long, because there is no telling how long these can be made at these prices. You cannot go wrong with HG's Econ line of quilts. Thank you HG for this amazing line! I am now the proud owner of two sets, one in 20 and 40.

  • Great deal!

    by Jeff – 3rd Apr 2017

    I was waiting until next year to buy an underquilt but when i saw the prices for the econ line I jumped at the chance. It is very light weight and packs down​ super small. It is easy to install and the 20* incubator radiates heat. I am really impressed how it keeps my legs and feet so much warmer then using a pad or down throw blanket UQ. i highly recommend this product.

  • Great Value!

    by Andy – 3rd Apr 2017

    First off... this UQ weighs just 3 oz. more than the traditional Incubator (comparing 20 degree quilts) so if you're counting ounces, there are lighter ways to invest. However, I believe this is the smartest way to invest... especially if you're just starting out and looking for high-quality gear. You just can't beat these prices! Highly recommended!

  • Top of the line "Economy"

    by Andrew – 24th Mar 2017

    Amazing quality for something that is labeled "Econ". The fabric is very nice, stitching is on par with any other Hammock Gear product. Thank you for making down quilts at a VERY affordable price.
