    ***On my very first trip with this set***

    I carried this along with a matching burrow quilt on a 4 day 3 night trip to Linville Gorge in NC in the last week of April. The lows dropped down to the high 20s the first night, then the low 30s the next night and finally the high 30s the last night. I knew going they were only rated for 40*, so I compensated with a hammock sock. The first night (set up next to linville river) I used my entire set up, Both quilts, the sock, a HG DCF tarp, down jacket, and a pair of thermal britches, and it was a success. Not only did i stay warm, but never even got CBS. The second night (again next to river, just further down)I left the tarp and my jacket off and it was a success again, with only minor CBS
    ( which come to find out was entirely my fault). The 3rd night (on top of mountain) I started in my wool pants and hammock sock, and jacket, and actually woke up burning up. I ended up down to just shorts and a tshirt in the quilts, and the sock unzipped. I couldnt have asked for better testing conditions, and I couldnt ask for better gear. I am beyond pleased with not only the product, but their customer service. Excellent communication and CS skills. I am fixing to order my last set of quilts to round out my collection (a 20* set) and will be the quilts i use on my thru hike next year

    Great Underquilt

    Posted by Brad on 11th Apr 2021

    The quilt itself is warm and lightweight. The adjustable ends are great for conforming to your body and holding heat in overnight. I have only used it once so far on a trip that did not get below 40 degrees overnight, but I was very happy with this underquilt and can't wait to use it again.

    Premium Incubator Custom

    Posted by Adam Kincaid on 16th Mar 2021

    So far I have used this on 4 trips and I am not disappointed. It is extremely warm and easy to set up, just make sure you understand how to make adjustments for different situations to get the most out of it. The warmth to weight ratio is amazing with this as well. Extremely happy with my investment.

    Premium incubator

    Posted by Scott Elliott on 18th Feb 2021

    Went for some goose down on Shugs recommendation, had been struggling to maintain warmth using climashield apex which left me thinking I am one of those cold sleepers...the hammock gear quilts changed my thoughts! Goose down really is perfect insulation and these are superbly well made quilts, super light, super compressible, super warm.
    I went for premium 850 with 2oz overstuff.
    Brilliant job HammockGear.

    Even better than my old one

    Posted by John from Austin on 5th Feb 2021

    For years I have owned a black 0deg F incubator. I love it -- I slept out one night at -10 deg F, and was warm (in a winter sleeping bag). Now that I live in Texas, I thought I could get away with a lighter quilt, so I bought a 20 deg F incubator. I love the color, I love the new way of marking the head and foot, I love that it fits my Warbonnet just the same way my old one does. I slept out in the yard on a 30 degree night, and it was arm and toasty. And, it will save me a little weight, and allow me to send my warmer underquilt off with my son when he goes to college up north next year.

    Perfection as expected

    Posted by David “ Jolly” Hannan on 28th Jan 2021

    I have been a customer of HG products for several years and, despite the one bridge style UQ I own from Loco Libre, my entire insulation line is from Hammock Gear - 40°F summer quilts (with ¾ length UQ), 20° shoulder seasons, and 0°F deep winter climate.

    From the design (body shaped and contoured for maximum torso coverage) to the craftsmanship, I would recommend HG to anyone. I have owned some of their Econ line too and they are incredible for the price.

    Unlike some other cottage vendors who will charge extra for draft collars, HG quilts are built ready to hang with everything you would need.

    UQ Incubator Custom

    Posted by Mason Lough on 15th Nov 2020

    Amazing quality and ultra cozy. Have only used in 30s so far, worked fine but it is a 10 degree. Interested to see if it keeps me warm in the lower temps because I could feel slight breeze during high winds in high elevation. Customer service for this company is unrivaled and I will continue to purchase future gear from HG! Thanks.

    Like a Womb

    Posted by Jake on 23rd Oct 2020

    As advertised, it is wonderful addition to the hammock system. I was pretty sick of using a pad, I am very glad to never have to use one again. I have been sleeping outside in my hammock as the nights have been getting colder(mid 30s and very windy), and I have been wearing only light bottoms, and I am SNUG, with a burrow econ 20 on top and the 20 underneath. I am done sleeping in a bed!

    Better Than Expected

    Posted by Wes on 18th Oct 2020

    I am very pleased with my Incubator Under quilt. . I got a zero degree and was concerned that it might be too hot for me down here in Alabama, but I am very happy the zero degree. I can easily shed any extra heat or tighten the quilt down to hold in warmth. I look forward to using my Incubator for many years to come.

    Superior Hammock Add-on

    Posted by TJ on 24th Jun 2020

    I added this to my Henn. Hammock and oh wow, huge difference, all the warmth and no wind. Packs smaller than the bubble pad I was using. No hammock should be without one of these.

    You want one of these quilts!

    Posted by Donnie T. on 20th May 2020

    I have not had a chance to hang with this quilt yet... Grrr COVID... But I ordered this under quilt after seeing the quality and value in the top quilt I ordered last year. My wife who is Puerto Rican was even warm in high teens with the 20-degree top quilt. Of course, I then had to order a 0-degree under quilt for deep winter. The quality is spot on not even a missed stitch and if the rating vs. warm is like my top quilt it will be comfortable even below 0-degrees. Also for those of us gram counters, this is the best value for the weight you can get for insulation.
