Have usually the size M and have them but bought in size XL, now it fits perfectly. It is very comfortable to wear and have already tried at first treks. Even if you are completely sweaty, dries the sweat on the surface of T-shirts. Had to wear it without replacement at a two-day tour. Had it only aired in the evening and did not smell of sweat on the next day. Have the same ordered me there twice, in black and gray.
