My wife and I use down botties for our winter (snow) backpacking trips. Super warm, very convenient for having to get out of the tent in the middle of the night to relieve oneself. But, arg, very slippery! Curious as to how people have worked around this problem?
They are Feathered friends booties by the way. They have an inner (removable) down bootie, and the exterior nylon has a waterproof sole.
