    Shirts were Perfect !!! Heavier construction than I expected which is awesome, and the print was also heavy duty and to perfect detail.

  • Excellent service

    My 2 shirts came out awesome!!! They created a talking point between me & my favorite guitarist GeorgeLynch. (At his final 2 AZ shows). He loved the shirts & asked his guys "why they didn't have shirts like mine?"
