Re: [Hammock Camping] D.A.M. vs Underquilt - Why Choose?
- Wow, only one reply. Either my idea isn't as exciting as it seemed
when I came up with it, or a lot of people are luckier than me (out
camping instead of here reading the board to avoid work)!
Thank you Bill for your reply though. I had seen your DAM in the
past, and I was thinking I might employ something similar. The only
issue I have to deal with though is the way in which you inflate
yours. Since mine will be embedded in an underquilt, I would not be
able to clamp the ends of each baffle. Also, with an unsealed end
when I am using it as a quilt, I would have the added problem of the
down getting out when I am using it soft. What I am thinking is that
all my baffles will have to be connected in som way, and inflated
through one or two valves, much like the professionally made DAMs.
Now I know I can heat seal both ends, but I am not sure how I would
attach some sort of cross tube or valve assembly that would still be
air tight and not terribly heavy.
I know this is going to be a lot more work to solve than either the
underquilt or a normal DAM would be on their own, however, I would
love to be able to have the flexability without the worry of choosing
which to take before I even get where I am going. I would simply
stick to the underquilt because I know I prefer the comfort of them
over the pad or DAM methods. The trouble is I live in a state that
is half desert, and I like to see what is over the next hill. I very
often have no idea what to expect untill I get there, and everything
I have is all about the flexability. To that end then, while I can
often hang my hammock even where there are no trees, sometimes I am
forced to ground. When that happens, I must have something else.
Therefor, I am willing to take on the extra difficulty of building an
inflatable quilt as it were. In fact, I think I will add the
following to the lexicon; IDUQ - inflatable down under-quilt. That
is my mission at this time, if anyone else has any thoughts or ideas,
please feel free to jump on it. I will need all the help I can get!
P.S. Bill, where did you get the poly-tube from? I am sure that is
answered somewhere on previous messages, but somehow I am missing it
when I search past posts.

I'm curious how to join the tubes together to ensure loft BETWEEN the
tubes. For example, a 2" sew-through quilt won't insulate as well as
a 2" baffled quilt because the thinnest point of loft is the sew-
through. Do you stagger the tubes? Or do you just deal with them
having a thin spot between them?
- That is a good point jwj32542, and it is thoughts like
that I am hoping to get, whether anyone has experience
or not. More people in the conversation means more
To address the question, at least in my case, I think
while the quilt is not inflated, it will act just like
any baffled quilt. When it is inflated, other DAMs
seem to be working for others without any insulation
between the tubes. Thinking about it, I think that
when weight is on it, the tubes smash a bit, deforming
from cylinders, to other less perfect shapes. Since
they are held tight together, I would bet that the
tops and bottoms of the cylinder curves expand out,
while the extreme edges (the only bit touching without
weight) stay the same since they are already tucked up
against one another. In this case then, I think that
the tubes take on a more square like cross section,
thereby insulating the space. At least that seems to
make the most sence since the tubes must deform some
way, and nobody with a DAM has reported any cold
strips so far.
Should it prove to be a problem however, I can add
insulation between the tubes too. The idea I have
basically is to have it constructed as similar to a
baffled quilt as I can, just with air tight baffles.
When used in quilt mode with no weight on it, it
should move and deform same as any other quilt. If it
does not, it would be possible to add down inbetween
the tubes. I really don't know though I suppose
untill I try. Anyone else have any thoughts or ideas?
Think it will work the way I imagine, or is there
something I am overlooking? I think I will order the
materials to start work some time in the next week or
so, I would like to have my plan completed. Thank you
all for your time.
Though I may die tomorrow, at least I can do it with the knowledge that once I did know true love -unknown
