I loved how my logo was printed, the quality was very good and the t-shirts themselves are also really high quality
These are a great sovereign something special my sons going to love them would definitely recommend thank you
This shirt did not disappoint; it was worth the wait! The quality is excellent and the material is so comfortable and soft. I ordered an XL (I am usually a women's M) as I wanted an oversized look. It's perfect!
Bought as a gift, not disappointed at all, quality and size is perfect, will order again
