The Shirt itself is a really nice, high quality material. Its quite thick and the colour is spot on whats in the pictures. The print is 100% what I wanted and the overall product is amazing. I ordered a 2XL which is already pretty big, it came a lot larger than I expected so next time i would order a smaller size, but thats down to me. It came just in time and the staff were super helpful in speeding up the shipping process for me so it would arrive on time. The printing turned out better than i could've imagined. I was very skeptical at first and wasnt sure how it was going to look, but it honestly looks awesome. So happy with it :)
