Simply perfect. I have the tech T, which is the short-sleeve crew version in this weight. I like the way the torso is fitted. The wool has an almost silky hand and is incredibly durable. Even on the rare occasions that I have overheated in this shirt I still never feel any moisture buildup. Wool has the advantage of moving moisture even befor it vaporizes, unlike synthetics. You can’t make a better clothing investment than merino, especially since it’s your next-to-skin layer.
By the way, I scored my shirt for $30 at EMS!
