yeah, I was just responding to ZDP's statement
the material that I plan to use is soft, breathable and very light - 30D polyester rip-stop. It will shed breezes and light spray.
That and cheap too, I want some!
The need for a tarp to cut wind was re-enforced for me last night. Inspired by a forecast for lows of 45 with no chance of rain, at 11 p.m. I was inspired to go hang. I set up completely in the dark, my headlamp was in the bedroom somewhere, occupied by my sleeping wife, who I did not wish to disturb. Anyway, I minimized the fuss involved by not hanging the tarp. It turned out to be windy, VERY windy, and I was just out in it hanging. Stayed warm with a Potomoc underquilt and a JRB Stealth quilt, until 5 a.m. Then I noticed that I hadn't snugged up the sides of the Potomoc using the shock cord provided for that purpose, so I was getting some moving air between the quilt and the hammock body.
Next time I'll use a flashlight when setting up in the dark!
