5’8” 155lbs lean build. Size small is a great fit for an undershirt. Really hard to find made in US wool shirts, glad to have found these.
Goal is to replace my old cotton and synthetic daily wear shirts with wool, but it’s pricey so will take some time.
I got these to take on a five day trip, I pack light so wore one on the plane and had one more in my backpack. Alternated days and worked out great.
Cotton shirts stink after just a couple uses and synthetic is not as pleasant to wear all day. Will be back for more.
