About the Incubator:

The ULTIMATE underquilt for guaranteed comfort...

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.

Product Description:

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.

  • Must-have Hammock Gear

    by Mike Mara – 21st Apr 2014

    Let me start by saying this is an excellent underqulit … I love it. I tried sleeping on a pad in my hammock and could never keep it in place and could never get comfortable. The underquilt completely eliminates both issues. My only suggestion to new buyers is to take the time to adjust it before you hit the trail. I have a Warbonnet Blackbird and sleep in the diagonal position. I found that my feet would push the foot end of the underquilt into the centerline leaving my feet uncovered. I made a line with a couple of s-biners and some elastic cord. I attached one end to one of the tie points on the underquilt go over the hammock’s ridgeline and attach the other end to the matching tie point on the other side of the underquilt. This kept the foot end of the hammock in place even with the offset foot box. I noticed that the web site now has Ridgeline Quilt Hooks … probably a more elegant alternative to my poor man’s solution.

  • The best in the business...

    by Pizza – 16th Apr 2014

    The Incubator20 degree to me is the best under quilt made hands down. The design is pure genius with the baffle construction and versatile suspension system. The Argon fabric options are the icing on the cake. This is the best under quilt I have used and I've used many other quilts from other vendors over the years but Hammock Gear to me is at the top of line.

  • Finally Warm in a Hammock!

    by Justin Huffaker – 15th Apr 2014

    This product has done the impossible... I was able to stay warm overnight in a hammock. Great product, great customer service, great people. Hurray for Hammock Gear!!

  • A work of art

    by Yukon – 10th Apr 2014

    Each and every time I get a new quilt from Hammock Gear, the quality of workmanship is simply amazing. I have never had a thread out of place, or problems anywhere else. It's always great to deal with them, and the prices great. Thanks again!

  • great fit and warm

    by Unknown – 10th Mar 2014

    What a great product! Top of the line materials makes this the best hammock under quilt. The elastic drawstring helps to create a perfect fit around your hammock to keep wind from blowing under you. i have the 20* incubator and have been down to 25* with no problems. you have to buy one!

  • You get your monies worth plus very knowledgeable owner

    by Carlos – 3rd Mar 2014

    I ordered this 20 degree incubator with 1 oz over stuff from HammockGear on the day after Christmas and it came in just in time for a trip I had scheduled. I have been able to try it out on three separate occasions now. Once in the 30s, once in the 20s and lastly once in the teens with a lot of wind so I am sure it felt more like single digits. I was perfectly comfortable in the two within its range and survived better than I anticipated on the lower end of the scale. I would definitely recommend this quilt as it is high quality and worth far more than what they are priced at. Call Adam and speak with him as he will guide you in the right path to find something to meet your needs.

  • Amazing !

    by Thos. Nelson Jr. – 24th Feb 2014

    Wow!The workmanship, quality and FUNCTION of this underquilt is absolutely amazing! I could not be happier with my purchase or the great customer service. Do not have any reservations about ordering an Incubator!

  • Don't hesitate... Push the button... Order one!

    by Garrett Jorewicz – 21st Feb 2014

    I am a gear freak, probably just like you... I can honestly say that this is the single BEST piece of camping/backpacking equipment that I own. The quality is unsurpassed by anything on the market. I ordered my 20 degree Incubator with 2 extra oz of down fill so that I can push the temp rating down closer to 15 degrees. I've used it in temps as low as 23 degrees and I was toasty warm all night.

    The key to making the Incubator work properly is to spend the time to get it setup properly. The first time I used it, I just hooked it up and went with it. While I was very warm at first, as it got colder, I began to feel a cold spot in the middle of my back. However, on my second night, after engaging the secondary suspension and pulling the UQ a little more tout, the cold spot was then eliminated. Take the time to dial it in and you will be extremely satisfied!

    As for the materials... Beautiful. Soft. Sexy. Love it! Stitching was perfect. You won't find a higher quality product at REI or any other camp store.

    That said, if you are on the fence or if you are hesitating for any reason what-so-ever. STOP HESITATING! Place your order and reap the rewards! Like me, you'll probably also want to compliment your 20 degree Incubator by picking up a Phoenix 40 (just got mine) for warm summer nights.

    You won't regret it.....

  • great products and people.

    by Unknown – 17th Feb 2014

    This puppy sleeps like a champ. And it arrived two days before our trip. This is a great product bottom line. Thank you hammockgear for the customer service as well. These are good people.

  • Get Incubated!

    by Kevin S. (Slammer) – 15th Feb 2014

    Got my incubator 20 w/ 2 oz Overfill this week and it's Nice!
    Fits my Hennessy Backpacker very well. I set it up first night for a test run. It performed flawlessly,
    Heating up like an electric blanket.
    The low was 29 and I used a 10* ZPacks on top and whew, nice and toasty. Had to vent several times.
    In short - get this UQ! Ditch the pads and foam.
    Quality and delivery is 5 stars! Customer Service 10+

  • Just buy one

    by Kapow – 13th Feb 2014

    See above^

  • Easy to setup, very warm

    by MattTaylor – 27th Jan 2014

    I got a 20 UQ/TQ and used it in 18 and 21 degree nights this week. Excellent product. I stayed warm and slept great. Setup was much easier than I expected, they appear to be built with great attention to detail. I expect to get many years of use from them.

  • My first Underquilt

    by Lyle Sinor – 23rd Jan 2014

    The Incubator 20 was my first underquilt. I shouldn't have waited so long! Craftsmanship is excellent - attention to detail outstanding. Have tried it with a Hennessey hammock on two occasions at temperatures around 20 with a good breeze - kept me nice and warm with a 20 degree rated topquilt and thermal underwear. Suspension was easy to set up and kept the ends of the underquilt close to the hammock. The camo also looks really nice!

  • Just the best your money can buy

    by George Carr – 2nd Jan 2014

    Got to use my Incubator 20 last weekend on an overnight hike. Temps were in the mid 20's and I was never less than toasty warm. What do I think about HG's Incubators? They're the best underquilts your money can buy - I should know, I've owned 5 of them!

  • Wonderful - accurately rated

    by Grouchy Redneck – 31st Dec 2013

    This was my first under quilt from Hammock Gear. It's absolutely wonderful - I can't believe I waited so long to get one.
    I got the 20-degree and added 2 extra ounces of down to achieve ~35% overfill. I've slept in this down to 14-degrees with a matching 20-degree Burrow. I wore lightweight fleece to bed and a fleece balaclava,. A tarp protected me from the wind. 14 is about the limit for me without a hammock sock - I sure can't complain about that!
    Adam is great to work with and happily answered question after question during his busiest time of the year.
    Thanks Adam, more orders to come...

  • great and easy to use

    by Scott D – 20th Dec 2013

    I ordered and received a 20 degree long version with 2 ounces of overfill for a DH TB regular length. It fits really well even on an asymetrical lay and I love the extra coverage of the long version even though it was unnecessary as I am only 5'10". The specs for my quilt were exactly 83" long and 44" wide and 27 ounces so I think he stuffed 4 ounces of overfill in and only charged me for two. I haven't had it on a trip yet but tested it in my backyard at 16 degrees and slept warm all night with a WM 20 degree sleeping bag as a top quilt. The quilt hooked up in seconds and was easy to cinch in tight thanks to a well designed bungee system. This will be my go to quilt for most everything but the middle of summer and the coldest days of winter. I am thinking of ordering a custom deep winter version that I saw on one of Shug Emery youtube videos when I save my allowance up again.

  • Survived in sub-zero Wisconsin winter.

    by Nathan Kilps – 18th Dec 2013

    I literally received the incubator 20 degree under quilt as I was leaving for a weekend winter camping trip. We were camping in the northern kettle moraine area. The wind and cold never touched me. My only problem was that I had to get out of it the next morning. Also the service and communication was fast and friendly. A+ company! Thank you and keep up the good work.

  • Great Product

    by paddlemule on hammock forum – 21st Nov 2013

    Got this based on a friends recommendation and have been nothing but happy with it. workmanship looks great. Obvious they pay attention to detail. Wish the draft tubes were just a bit fluffier but has not failed to keep me warm on two 30' outings. Definitely like the full coverage. Thanks again for a great product.

  • Top quality

    by Eric F – 18th Nov 2013

    I didnt have any custom requests or rushed delivery or anything. I just ordered from the website and they came a week or so later. I bought two of these and you can tell right away they know what they are doing. The construction is excellent. The suspension is very well thought out and i find no need for any triangle things or any additional support for my diy, Hennessy, Clark or Warbonnet hammocks. Probably going to buy a couple more for the rest of the family. Only had it down to the upper thirties and was toasty but its fluffier than my 20 deg sleeping bag so im not worried if the temp drops. Like i said probably going to buy a couple more,

  • Amazing! Simple and warm

    by PatrickM – 14th Nov 2013

    As many have said I was skeptical of spending that much money on a quilt, but now that its here Im very glad I did. I've had a few restless nights in my hammock sleeping on a ground pad...have to readjust the mat, weird folds, and just being uncomfortable, but with this you just snap it on, tighten it up a little and you're good to go!

    Couple the easy and comfort with the quick email responses and fast delivery I will be purchasing a top quilt from hammockgear very soon,

  • Satisfied bigtime!

    by Christina – 6th Nov 2013

    The is my first UQ. I was a little skeptical about dropping the bucks for my Incubator 20 , but thrilled I did it. This sucker is so warm and toasty. I'm excited to use it on future hiking / hammock camping trips. The service was fast, friendly and very satisfying.....so satisfying that I also bought a top quilt, the Burrow 20 and I'm loving it as well. Thanks Hammack Gear!

  • happiness is a warn nest !

    by Danny slaughter – 2nd Nov 2013

    Thank you ! I received my incubator 20 . Right on time for a fifteen day fishing trip . Rain, wind, low30 deg. Nights .
    I had a learning curve to keeping my quilt in place, but after that I slept warm every night! Now I need an over quilt. And I definitely will be giving these guys my business ! THANK YOU.

  • Great gear and Great Customer Service!!

    by Cole H – 23rd Oct 2013

    I called the Guys at Hammock Gear and he was very helpful. We talked for about 20 minutes about what would be my best option. And being a down home type of guy, he didnt try to sell me on the most expensive piece of gear he had. He asked my height, weight, type of hammock, what type of weather....etc and together we made a choice.

    I opted for the 20 degree incubator. after 2 weeks of prancing by the front door it finally arrived. And let me tell you, that piece of gear is artfully constructed. I have not had a chance to use it, but i went in the back yard and laid down on the patio chair and used it as a blanket. in 40 degree weather, it was amazing! i was so warm. Also, he gave me a small discount which helps a poor guy like myself. I will most definately be ordering my top quilt from them when funds permit!! I cant wait to actually get the rest of my gear together and use this thing in the bush!

    If you are considering an underquilt, but aren't sold yet, give these guys a call first. very friendly, helpful and just down right awesome!

    Thanks HammockGear for the help and the product. My roommate will be buying some stuff in the near future also from you guys. he was so amazed and how light and how warm it was.

    Thanks again!!!

  • Great product and outstanding service

    by Steve Ross – 11th Oct 2013

    Hammock Gear was very open to my request for expedited delivery due to an upcoming camping trip. My Incubator arrived 2 days earlier than expected and in plenty of time for the trip. I needed to purchase S-Biners to hang it on my Warbonnet Blackbird, and the suspension is less than intuitive (to a novice like me) but once it was on the hammock it was amazing...so warm and no issues with coverage, air pockets, etc. The product is extremely well designed and constructed. I am so happy with the purchase and would recommend the Incubator as well as Hammock Gear wholeheartedly.

  • Magical Quilt of Hope and Wonder

    by Ryan Barker – 1st Oct 2013

    I bought an Incubator 20° for my Warbonnet Blackbird. It only took me a few minutes to make my proper fitting adjustments, and now it fits perfectly and sets up in seconds. Wonderful. I haven't used it in super cold weather to test it- my trip was 40°. Nonetheless, I was toasty using just a light weight 40° summer bag. I was very pleased with the results. Plus, HG expressed shipped my quilt just to make sure I had it in time for my trip- two thumbs up!

  • AWESOME!!!!!!

    by Mark Rulli – 27th Sep 2013

    Don't know where to begin. This is the lightest bag I have ever owned (12 5/8 ozs with cuben fiber stuff sack). The quality of the construction and materials is as good or better than my MontBell or Western Mountaineering bags, no easy feat. I used the bag on a recent trip that was in the low 50's under the Zpack Pocket Tarp. It was rainy and windy all night, but I was warm and more importantly COMFORTABLE. I didn't even have the foot section pulled tight. How you guys make such a great bag for such a reasonable cost escapes me, but just keep doing it. Thanks for making my new favorite piece of gear.

  • customized Inc 20*+2oz long version in Switzerland

    by Chris (HF: pravenda) – 27th Sep 2013

    Rhight out of the box, I've started indoor testing: setup was quick and easy. The longer version match perfect to my length and the length of my DH DB 11'. The smoothness of Argon and the little weight is fantastic. Outdoor Test start at this weekend, but for a real test it's way to hot. By the way: I got a Blue Mauritius: HG Logo is upside-down. It doesn't matter to me, but make this piece of excellent gear somehow more specialized. Great Job, Adam and Jenny
