Big fan of the Animal line, this iconic t-shirt is comfortable and motivational. The only issue is, it tends to fit a bit large (so if you feel comfortable in a large, get a medium, etc.). I wear this shirt when I workout and I love it. Comes in two colors: yellow and red. I got a large, even though I wear a medium, to give me motivation for building muscle. At a great price, this makes a good gift for any fitness guy!
