Not as itchy as wool, but more itchy than many other merino wool products we've worn. My husband says he notices scratching but it doesn't bother him; Someone with sensitive skin will likely find it too itchy. On my skinny 6ft 2in husband this looks very attractive. It's not baggy or tight, and the color is attractive (IMHO). Good for training in cold weather as it breathes well. But that's JustMe.
