The good old high tech classic. Breadbags between layers of poly dress socks! Cheap and effective. As for constant ly wet feet...I change out my inner socks daily at bed time. Feet get a chance to fully air out before going to sleep.
Thanks for the reference to the RIBZ. I'd never heard of this pack and Goggled the term after reading in in your response. I checked out the site on line and ordered one today. I think it will extend the use of my Osprey mountaineering day pack.
Most of my winter layers are a bit large so it works really well inside to keep all of my food and water from freezing for the day.
I just add more in the evening and let it thaw as I wear the pack to bed.
This post needs an update. Lessons learned?
My boots go on the Black Bird shelf, sometimes in a plastic bag, often enough not. The boots don't stay warm, but also don't fill with snow, so I'm happy.
Alcohol, water & electronics in quilt with me (My cell is an antique, so it HATES the cold) & as I carry minimum, am probably wearing all of my clothing or using it as a pillow.
The rest stays in my pack hung from the suspension at my head. Except for the rare times I hang my food "From bears" (about 1 in 8 nights in bear country, yea I know.)
Not sure I'll light my boots on fire, but I'll happily watch someone else do it, , , , , , from a safe distance that is. :D
The camera had to be kept inside my first base at all times as the freezing point at under -30 (-22f) was inside 2 layers of clothing.
Boots were warmed in the morning with warm Nalgenes from the hot water bottle from the night before.
Insulation was kept moisture and ice free with 2.5l of hot water kept inside my Wiggys sleeping bag at all times when hung and not travelling.
Vacuum flasks dried any residual moisture the boots by being stored upside down in my boots and the inbuilt snow collars cinched closed to stop snow getting in.
My derriere was kept happy with dried wet wipes soaked in boiling water and used before they froze solid.
Zebralight Headtorch was adapted to take external power supply from a battery pack kept down my neck.
Axe handles had to be wrapped in gaffer tape as at -30, the handle became lethally slippery.
