The Jacks ‘R” Better Nest is an 800+ fill power hammock underquilt that fits under your hammock and provides much-needed insulation on your back when the temperature gets colder. The quilt weighs 20 oz but compresses down quite nicely in your pack. Like the Hennessey, it has a birth canal style opening that mates with the hammock’s entrance, and Velco strips which attach to the Velcro strips on the hammock itself, which makes it possible for you to easily slip out during the night for a pee.
I spent a significant portion of this year experimenting with different insulation options for my Hennessy Hammock in order to extend its season for optimal use into the early spring and late fall, and I must confess that I fell in love with the JRB Nest, Down Under Quilt, shown here on my Hennessy Asym in the Adirondacks.
The nest attaches to the hammock using mini carabiners and line that JRB calls a suspension kit and weights 1.0 oz. If you choose you can guy line out the nest’s sides, but this is not necessary, and you will stay warmer if you don’t because the edges of the quilt will come up higher on the hammock’s sides. Using the nest, it is possible to not bring along a sleeping bag and just use a top quilt. I haven’t tried that option yet myself, but it is a viable alternative for saving weight.
Priced at $295, the nest is a sizeable investment. But I found that using the quilt eliminates the need for all of the new underlayers that Hennessey came out with this past year (and which do not stay in place), and the need for any other homemade pads or emergency blanket gizmos you can think of. I sleep like a baby when I use my JRB nest and highly, gushingly recommend it if you are a hammock enthusiast.
