BarberMike,
glad you found us-the ones in the airships
You've probably already figured they are several completely breathable socks out there that require a tarp or to be used when its seriously cold that all precip is solid and will fall off the sock.
We wanted a sock that can be used year around without regard to temperature--well except when tis just too hot to use one.
We've made leaps of progress manipulating cuben and breathable cuben and momentum 50. I think we are on the verge simply because Hangnout's mind never stops.
He's already working on the 3rd gen sock based on all that we've learned over the first two-the Dirigible and the Graf.
You've already guessed that cuben and w/b cuben are outrageos in cost but Hangnout this past weekend on the Big South Fork hike unveiled what promises to be an affordable (or more affordable than wb/cuben) version.
Stay tuned for the 3rd gen's unveiling sometime this winter.
Condensation is a hard reality but there are tricks up Hangnout's sleeve.
