    UQ Incubator Custom

    Posted by Mason Lough on 15th Nov 2020

    Amazing quality and ultra cozy. Have only used in 30’s 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 30's 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'm done sleeping in a bed!

    Better Than Expected

    Posted by Wes on 18th Oct 2020

    I’m 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’m 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.

    0 degree Incubator and Burrow

    Posted by Laura on 5th May 2020

    As a ground dweller I would use a synthetic 0 degree sleeping bag stuffed inside a second identical bag on a cot with a 3 inch foam pad. When I decided to convert to hanging I knew I had to find an exceptionally warm set of quilts. After a long search I found HG. They had the highest down fill I could find and all the best reviews! So I decided to give it a try. I ordered the incubator and burrow with a 0 degree rating and 4 ounces of over fill, for good measure I added the under quilt protector. To my delight they arrived 3 weeks earlier than advertised on the website. The Quality is indeed top notch, even to someone who sews wedding dresses, prom dresses and patchwork quilts. I can see the detail and care that has gone into this wonderful set. And yes they do keep me warm! No small feat.
    Thank you HG team for making hanging a reality for me!

    Worth every penny!

    Posted by The Bandit on 26th Feb 2020

    This is hands-down the finest and most well made piece of gear I have ever had the pleasure of owning. Just incredible craftsmanship. Performs fantastically well, full coverage warmth from head to toe with no drafts. And it looks so good I want to hang it in the living room just to look at it. Pull the trigger on this one.

    Very Nice!

    Posted by Michael P - Dallas on 22nd Jan 2020

    Purchase details: Temperature Rating: 0°F (-17°C), Length: Long (6'2" to 6'7") (187 cm to 200 cm), Fill Power: 850, Overfill: Standard Fill).

    I purchased this product believing I would receive something that was just for me, and that expectation was fulfilled. This is truly a premium product!

    At first I was concerned that the width was not enough, as I have broad shoulders and like to feel encapsulated. However, after taking this out for multiple 20 degree nights I can say with confidence this product performed flawlessly.

    On my next purchase (oh yes), I will probably special request an additional panel on each side for additional comfort (as a luxury, not a necessity).

    Thank you HG!!
