I got these I ran them through the laundry. They didn't seem to bleed at all. I like short sleeve because when I put a long sleeve on under a shirt the sleeves bunch up behind my elbow and I have a hard time pulling the inner sleeve forward. My only complaint is there is no neck tag to indicate which side is front and which is the back of the shirt.
