This is 100% merino wool and is very soft. I've worn it about three time and, so far, no pilling. It runs larger than some of Smartwool's base layers and jackets. I am 5'8", 140 pounds, and wear a large in the baselayers, but they are form fitting. I got a large in this sweater and it is roomy, but not huge. I probably could have gotten a medium.
