It appears to me that science gives us/them 2 selections: Our entire body sweat(liquid) can evaporate to vapor- leading to evaporative cooling- off of our skin and travel into our insulation, or sweat is often wicked into our insulation in liquid sort as It will be that has a sponge. Which retains our skin feeling pleasantly dry! Our physique vapor(not liquid nonetheless) just travels into our insulation, and we/they hope which the vapor(forget about sweat, by now liquid) will continue likely for an inch or three or 4 instead of come across the dew point In the shell and condense again into liquid. Hopefully, that vapor will just keep on heading earlier that breathable shell in to the atmosphere which might previously be 100% humidity(vapor travels from significant humidity to lessen, ideal? Not from decrease(near the skin to increased- outdoors the shell probably presently one hundred%). that's the target, and at times it works perfectly, Though they remain coping with evaporative cooling within the skin level. If it doesn’t perform completely all the time, then night time just after evening, some vapor hits the dew place and condenses into liquid, or their sweat receives absorbed into their down, and loft decreases working day right after working day, if no sun is handy for drying. sometimes all of this freezes into ice In the down!
