I've owned the black version
"I've owned the black version of this shirt for the past two winters, usually every day. Being Merino wool, you don't have to wash it very often, as in once a month, maybe. It seems to regulate my body temperature very well in a variety of conditions, and I've worn it on long rucks in temperatures down to 29 degrees F. Being wool the shirt can build up static electricity and it is a lint and pet hair magnet, but the pros are worth those few cons. I'm 6'0" and 175 pounds, athletic build, and the large fits me perfectly."
