I liked the video as well. It would really be interesting if the two guys switched and jumped in again. Was it just their personal physiology or the materials? I suspect the materials, but that would have nailed that door shut!
i used to use merinos as a base layer but have gravitated back to synthetics. I still find merinos get itchy by the end of the day and they seem to dry slower as well which now makes sense after reading this and watching that video.
I do a fair amount of pheasant hunting in temps from +40 to -10 with occasional hunts as low as -24. On monday, I finished the year on a -8 degree hunt. Wicking is sooo important as you will sweat pounding cattails.
