So let say its cold, raining, and really windy, you just hike up a very steep mountain and you are sweating like crazy, then the wind starts blowing on your way down the other side of the mountian. How do you keep warm when you stop for a break or while hiking on a flat surface if your still soaked from sweat even though you have raingear on? Or what if its not raining and its just cold wind after you have been sweating for awhile? Thanks.
