    I understand the role that calendaring has in breathability, but I mistakenly thought that dwr treatment also affected this. So dwr only addresses moisture, huh? Thanks for your insight.
    correct. threadcount would also effect breathability but the calendaring effects it alot as well. i've noticed a pretty substantial difference in breathability between non-calendared and highly calendared 30d

    I kind of went off thread topic with that one, but it just struck me that if heat is lost because of the flow of air around the sock, would we lose less heat if we disrupted that flow and created turbulence around it, perhaps by adding some hanging ribbons or Ben Hur-like spikes? Hehe.

    My guess is the gain would be minimal, but I have no real idea.

    Maybe someone on here is a thermal engineer and could weigh in. Until then, back to fabrics!

    So............

    Making a sock with a DWR finished bottom and an "uncoated" top would NOT increase breathability unless there was a significant difference in the weave or calendering of the uncoated ripstop.

    Or, no condensation penalty in going all DWR treated fabric according to above discussion.

    Not at all what I had thought.

    I hate when facts get in the way of a good idea.

    correct, might as well use dwr all over and pick the level of calendaring or lack thereof to effect how breathable/wind resistent it is.

    If I use a tarp with doors to cut wind flow to the hammock sock, would using the Magna 1.0 trap the heat or is the material weave too lose and won't do anything?

    i'm not familiar with that fabric. i suspect it would have to cut wind somewhat, even noseeum netting does to some degree.

    I used the Magna 1.0 as a top cover for my WBBB and it definitely holds some heat! I love it and it's about as good as it gets for preventing condensation. I will note however, that my overcover is attached to the hammock with velcro tabs and acts like the bugnet. In other words, it doesn't billow in the wind like a sock might.

    As did I. I sent the fabric to AHE and had them make my BBO with it.

    While it definitely blocks a fair amount of breeze and holds a useful amount of heat, those asking need to understand that the tighter the weave is and the heavier the fabric is, the warmer it will be (even a bug net blocks a little wind and holds a "little heat").

    With that said, the Magna "1.0" ACU has a very nice balance of heat retention vs. breath-ability for my use. I am going to try a cotton muslin fabric (have a roll for other uses) for well below freezing use. It may be a bit too loose of a weave...time will tell.

    I just found a bolt of canvas-like material among my grandmother's things, back in the closet where I found the sewing machine the other day. Measured out it is 9 feet by 64 inches. It is grayish green, like an old Army uniform. It is not light but if it's long enough (should be) would make a good weather sock for my hammock.

    There's some muslin-type material here, too, but of no use that I can see, too narrow. Scissors, dull. One of those tailor's tapes, worn out. Zippers, look good. Mercerized cotton thread ... ??? Needles for the machine and three more bobbins ... cool!

    Ah, my wonderful grandmother ... Corinne ... I named my second daughter after her.

    My goodness ...

    Want to make that sock out of this that I found today ... and remember her.

    You guys would not BELIEVE the Christmas dinners she used to have for us. We all helped but she was the leader and inspiration, a true Southern lady.
