Great Quality
Color: Black, Size: Small
My son loves these shirts. We have them in several colors. They are so soft, light weight and wash great. He is in college and he can throw them in the washer and dryer and not have to dry clean them which is a plus for him. They are slim fit and hold up well. One he has had for 2 years and it still looks great. Great value for the money.
