Use Coupon code “Free Shirt” during checkout once you have added at least $100 of product into the cart. These t-shirts are made of a very soft durable cotton from Next Level Apparel. They come in a gun metal gray color. It tends to run as a slight “slim” fit meaning it's a little bit more snug in the shoulders and arms. They are a good long length for men but run a little snug. If you like a loose fitting shirt then I would say order one size up from what you normally where.
