Best. Shirts. Ever.
Size: 3X-Large, Color: 3 Pack-black
These are great t-shirts. They fit great, very lightweight but not cheap-ish. There is some sort of stretchy material mixed in with the cotton which is good. I like my t-shirts a little bit large, so i ordered the next size bigger. I have since ordered 2 more packs of these shirts. Would def recommend. A+
