Glad that there is a product I can wear that isn't made in China. This is not expedition weight, but rather medium weight. It runs a little on the smaller size. I would normally wear a large, top and bottom, but found it necessary to order an XL if I am wearing next to my skin.
I am trying out something called fishnet underwear to wear under the wool underwear (vapor barrier and keeps cold wet away from body). With other merino wool, I would wear an XL with the fishnet and it would be comfortable. This however, with a size XL was a little less comfortable after the wash. I prefer to have my long underwear not too tight against the body. In the event of using the fishnet underwear, I would almost prefer to go to the XXL. Good product though.
