Nice heavy duty long sleeve shirt
good looking and good fitting long sleeve shirt. I didn't notice the flag on the sleeve until I unpacked it. Nice touch. Color is true. Material is indeed stretchy. I cannot determine the fabric blend but it is comfortable. The care instructions are included on a card, not on a tag, not be sure to pay attention to it. I am 5'10' and 235, the 2X fits me well.
