AWESOME!!! I bought this shirt for my boyfriend because I loved the design but I had no idea that it would be so soft and so well put together. Thank you so much, exceeded expectations. - Casey H.

I ordered this shirt for my best friend's birthday who happens to be a geology major! The shirt came very quickly, was super soft and looked even better in person! - Kayla S.

Thank you for the amazing product! It was prepared and shipped fast and I was in excellent contact with the shop the entire time. The shirts are very high quality, soft, and true to size (a little stretchy too). There is nothing that could have gone better! - Madeline O.
