I have never bought any clothing made with merino wool before. Normally, wool makes my skin itchy and red. First time I put on this shirt I was a little taken back by how it felt. It wasn't as smooth against my skin as it was when I felt it with my fingers. BUT, no itchy skin and no redness! Also it felt nice on the second wear. I also love the length of the shirt. It covers my bum completely. I'm 5'3, 125 lb, bought size small. I would definitely buy more.
