No ventilation hole. That was one of the things I wanted shug and cavediver to determine - whether a vent hole was necessary with the breathability of this fabric. The way shug is using it, apparently not. I still like a sock better than a topcover, but for a lightweight option, it does the job of keeping in a little extra heat.
The extra weight difference between your SS overcover and this is probably from the ggr end tabs and shockcord/cordlocks. I really have to work hard to think like a gram weenie. I've never seen a SS overcover, so it would be interesting to see how they compare.
Hey .... slept out last night ... making a video .....and used the TC un-vented (I pull the head end back to vent) my 0º bag, Thermadrape sewn to my old weather-shield of ripstop nylon, UQs and finally DriDuck poncho weather-shield. Slept really warm!! Some condensation on bug netting (pulled back over shelf) and a bit on the TC. Expected that.
*Had some moisture on my hammock material under me and the Thermadrape felt moist ... but I was truly warm. The ol' Shug is a heavy sweater!
It was really windy last night and the TC did a FANTASTIC job of keeping the wind off of me and did retain a little heat but not as much as a sock would.
For my money keeping the wind off is worth using it. Plus I am liking camo now.
Sweaty yet Warm Shug
shug, I'm pleased as punch that you like the topcover. PM me if you think there are any design "tweeks" that you'd like to see done.
FF are you gonna post directions for the OC?
I think I remember you saying you were not going to sell them, but I would be interested
if you change your mind.

Hey Fish Is the top cover waterproof? It would be neat to have a form fitted one as a tarp as well.
counselor ... are you thinking to use only a top-cover as sort of a mini-tarp? I have an old hammock that incorporated that idea. It sorta worked in some conditions.......
