I'm waiting anxiously for any news on the AirShip because I hope to get 'winter' time it is and then progress with it into the spring. It shouldn't be long though before I can give it its due.
Yes many many nights in socks now. I think I'm right at 40 nights in either the Dirigible or the Graf. But since I've been in the Graf Poof has been in the Dirigible and we've gathered good info because she and I are different sleepers in regard to moisture output.
I guess you already figured out that almost every sock out there has condensation/single wall tent issues. It is the hard reality of enclosed spaces that are warmed then filled with a gas full of moisture, then pushing that moisture laden air against a cold surface.
I say almost because I can't speak for the cotton socks like are used in the super cold north; and has already been pointed out our area of southwest Va/east TN/western NC is an especially challenging environment.
So the differences between the two socks I've been testing (Graf and Dirigible) has moved from a direct comparison of just the two socks, to a sock with a 'wet' breather -Poof, and a sock with a much less 'wet' breather -Me.
We've also noted and pointed out what we're calling CPC=contact point condensation.
This phenomenon is nothing new and almost everyone who remembers canvas tents of the past (for me in Scouting years ago) knows that when in a canvas tent in the rain and you put a finger on the canvas it begins to leak there.
Well the cuben/waterproof-breathable cuben does not leak but over the night if your sleeping bag touches the material condensation will more likely happen there.
Poof has had more condensation in the sock with the most breathable cuben, proving at least to us that she puts out more moisture through the night....we'd have guessed that because she puts off more moisture when climbing the hills with a backpack too.
So condensation is something to think about and deal with. I read about it happening with the latest Warbonnet sock. I experienced it in a very frozen form with the MacIX sock in the guise of a mini-snow shower inside the sock when I woke up at 9F and tapped the inside of the sock. So one question begs to be answered by most any potential sock user--how much condensation can you deal with?
After all is said and weighed (and weight is hugely important to consider) I'm converted to sock use. For me the condensation is so far minimal--thought I can
tell with approx. 12 nights in the Graf that the amount of w/b cuben is now at its
minimum for even me a 'dry' breather.....and yes the amount of moisture you put off
breathing is considerably more than what transpires off the skin.
So this could lead into a giant epistle on methods of dealing with condensation but that would also (a good thing) lead to proper use of a sock and luckly both the Graf and the Dirigible were provided by HNO's great design many ways of using based on the conditions you find yourself in.
Example, on one of the Smokies hikes it ended up above 40F at bedtime...well my sock is also my tarp so the tarp portion was deployed but the sock portion was simply pulled to the side and staked down forming the other side of the tarp....
Compare this example to the time on Mt.Sterling when I didn't have quite the insulation I needed and fully battened down the tarp portion wrapping it around the hammock fully enclosing the whole enchilada. Even in this mode I had little condensation but I bet if Poof had been in it a different story would have emerged.
When I look back at sock use there was on the time when the temps were 97F and up that I've not used one. That said I'm eager for the Roan Higher/Colder hang to see how either the Graf or the Dirigible ....or if we're lucky... the AirShip performs fullen enclosed in single digits.
When do socks really shine? We'll you've read about and HNO and I've both pointed out that its greatest feature is the 'one-bag' solution and the super super quick set up time. Another place it shines is in huge winds just because they are so aero and because of less lines to deal with in the wind and when packing up.
Condensation and wind though really go well together-even when fully battened down, wind just helps more moisture.
Speaking of. I keep a fan running in an enclosed room..like moving water is harder to freeze, moving air is harder to condense
Methods to deal with condensation. OK, not wanting to write a tome here. Know this, with the HNO sock models you have various degrees of enclosing. Enclose as much or as little as you want or as the environment dictates...the more you enclose the greater the chance of precipitate. VBS=vapor barrier suits could be used (though I hate them), the SBC=Shug Breath Catcher will help enormously.
I could go on and on.
Thanks for your interest in this project. It really has been fun and of great learning. Hopefully that will continue in the 3rd gen sock. I bet HNO will get to this thread eventually and tell us progress.
