Double bottom hammocks and shells
- Hi Coy,
You have hit the nail on the head.
Ray's insulator and the double bottom hammock as I built it are
different and meant to be so.
Ray's insulator (and all the taco shell derivatives) are relatively
loosely hanging under the hammock to allow use of leaves or air bags
or clothing or packs or space blankets under the hammock. This is
really not too far away from the idea of an underquilt that some of
us have experimented and Ed's pea pod under and over bag.
I had some difficulty with the underslung insulation which I did not
have with the pad in the hammock. I found the insulation, if not
against me, tended to get wind or convection currents going which
robbed me of warmth. I wanted the equivalent of a pad against my
skin so there was no room for cold air to get in.
However, I find several of the pads uncomfortable because they are
sticky to my skin and tend to bunch up and move around a lot when I
toss and turn. I especially do not like the inch wide radial folds
that form in the Target pad half way through the night, poking me in
So, when someone mentioned the double bottom, and I remembered
reading about this type of bottom on the Crazy Creek H, I decided to
give it a try. I worried for a moment that the two hammock pieces
would compress the insulation into nothing, and then remembered that
I was already sleeping with all my weight on the pad anyway...
My observation from a couple nights sleeping on this system is that I
can move around easier; moving around does not move the pad and
uncomfortable folds do not form in the edges of the pad, the
insulation is against my skin (except for a single layer of cloth)
and this keeps me warm.
I do look forward to reading the results of the double 1.1 oz hammock
in these reports. I will build a double 1.9 oz hammock because I
already have the material coming.
I have done a couple calculations. If one builds a double 1.1 oz
hammock but makes the hammock 48 inches wide, it will be 93 percent
of the weight of a standard 60 inch wide 1.9oz hammock.
BTW, I did take some pics last night with my son in the hammock, but
the connection with the computer is on the fritz... Soon will come
the pics, I promise.

I've had the best cold-weather success with a double layer
hammock and a Speer Pea Pod. I think I'm going to try the
Garlington shell next winter as a method for attaching an
underquilt, and use a smaller, thinner quilt on top. Same
idea as the Pea Pod, but just not a wrap-around.
- I gotta try a "pea pod" next winter! Experiments with narrower
hammocks might decrease the empty space in the bag, making it more
efficient (and lighter to boot!)
