Re: [Hammock Camping] Tyvek as undercover or weathershield
- Hi Neil,
I tried the tyvek as a weathershield outside the HH and JRB nest. A few
times, it really seemed to work. It was on one night with a soggy fog
that left my damp socks dripping water that I had trouble with
condensation inside and outside the tyvek. Really, both sides of the
tyvek were covered with water droplets. This meant the down of the JRB
nest wasn't able to do it's job. Removing the tyvek may have meant some
water on the nest, but the result actually was warmer. Maybe one of the
truly breathable (i.e. perforated) tyveks would work better.
I had also tried mylar between the nest and the HH. This resulted in a
pool of water (several ounces, actually) of condensation on my side of
the mylar--meaning I got wet. This, too, was during a night with a
seriously soggy fog.
I've camped in sites where these soggy fogs turned into freezing fogs,
leaving everything on the windward side covered in 3 inches of Rhine ice.
Because of these experiences with soggy fogs, I'm now very leary of
using any non-breathable weather shield (or splash-back shield) with my
hammock. If it can't breathe, there's going to be an astounding amount
of condensation--at least in Taiwan at elevations >2500 m.
If condensation wasn't a factor or if I needn't worry about the soggy
fogs, I'd think the tyvek was a great weather shield. As it is, I want
to carry gear that's going to work with all conditions, not just special
During that night of the soggy fog. After I removed the tyvek, the JRB
nest worked fine to keep me warm. The next night was clearer, a little
dryer (still some rain), and a little colder (from about 10*C to about
4*C). That night, I just couldn't seem to get the nest adjusted
properly. Adding a partially inflated 3/4 thermarest inside the hammock
worked fine to keep me warm. No condesation between me and it, either.
I found that 3/4 lenght was easy to handle in the hammock, but did not
help keep my feet warm. Either I had to ball up on the thermarest or my
feet got cold. I did not have a problem with cold shoulders. The
insulation from the nest seemed to work find for that.
who sleeps cold--very cold.

- Cara Lin,
Have you thought about adding a "solid barrier"
between you and the soggy fog?
Perhaps Ed's 10' x 11' Winter Tarp?
