Gargoyle pointed out the obvious I didn't see--on the whole trip is never rained while hanging, a bit while cycling which was a blessing SO just got back from Walmart, going to take a little nap then deploy the sprinkler!
Breathable bottom vent-maybe Hangnout will chime in here, hope so, but I'm thinking (maybe wrong) that the w/b cuben is directional and moisture/water can go one way out. The entire structure is fully taped so no fear of leaking directly and the 'hoods' where the sock gets 'pulled' out along the suspension is another brilliant design feature that removes an doubt of water getting in that way.
I'll post a short vid of the sprinkler test later tonight.
Bill you are so right, its almost log growth in the developments in the last few years.
MAD, nothing wrong with the separate tarp-it still gives you more variability in set up...we thought of doing that with the asym cuben from Zpacks but my main mission was a quick simple setup with NO lines to deal with at all, of course other than the suspension lines.
