That shelter you are using in the snow photo with the mammut red jacket looks awesome. what's the deal with that?

There has been no testing of this idea. If someone knows this is not a workable idea, please speak (even if this is just opinion).

We all agree that the quickest way to dehumidify a jacket is simply to undo the front enclosure. As has been mentioned, this is not so practical in a deluge. So, the thought goes, is it practical to create an "airlock" system?

Here's the idea: You have hiked for an hour, and are starting to swim inside your jacket. Take out your trusty multipurpose plastic trash bag with a hole in it. Throw it on over the top of you (head goes in the hole, pack is off). Lean forward and open the front zipper. Allow steam to escape into the "airlock" you are creating. Close the zipper. Remove the trash bag. Repeat as needed.

If someone has the equipment (and time/desire) to test the efficacy of this idea, post your results. A guess, is that the requirement to stop and do this every 30 mins to an hour may reduce any interest in doing it at all.
