I stole your hammock sock idea for a 10-day paddle down the Cape Fear river recently. Just sewed 2 sections of 45" fabric (about 10' long off the top of my head) along the long edges and put drawstrings on each end. No tapering, but it took all of 10 minutes to make. Even used it as a bivy on top of my groundcloth one night when they were calling for below-freezing temps.
Superb protection, and condensation was minimal with a ridgeline.
Now, I got to thinking while hanging there about how to make that into a summer sock. It hangs enough from the hammock that condensation "shouldn't" be a problem if the bottom was all sil-nylon. I'd also make 18" or so of the top out of silnylon for spray protection on the ends. Make the rest of the top out of tulle or no-see-um, taper one end to about 6" diameter and leave the other end full width for easy entrance/exit. From the top it would look something like:
I silnylon Tulle / noseeum silnylon
\ XXXXXX XXXXXXXXX
The drawstring at the head end allows for stupid easy entrance and exit and a good seal. I'm not even sure it if would have to be 100% shut as long as there was some fabric up there to seal the end.
If condensation turned out to be an issue, I'd just do the bottom in .75 oz fabric or noseeum - which ever was lighter. I'd still keep the silnylon end caps though.
