Dry the shell? Are we all talking about a hard shell layer or are some of you talking about soft shells (something I rarely use hunting)?I used to do some alpine climbing BITD and the standard practice was you'd throw your puffy/insulation layer on over your shell once you got to the belay. This system would use your body heat to dry out your shell and additional layers while you were stationary. When it was time to climb again, you'd simply remove the insulation layer and get moving.
