Great for wearing under my scrubs. Thin & lightweight. Covers a tattoo on my forearm & keepse from being cold. I'm naturally cold always. But doesn't allow me to get overheated when working. Thumbholes are not an issues size wise bit due to repetative handwashing I don't use them, I cuff my sleeve & push them up. Shirt is form fitting to my and arm length is a perfect fit. Length of body of shirt is longer, so I have to tuck it in my scrubs bottoms but I have a short torso, but it's no problem at all. Will but alot more colors.
