Colors dont match photo on Grey shirt

For the grey shirt, the printing on the shirt is opposite of how it appears in the photo online. In real life, it appears to be neon pink with a thin gray line.

Great shirt

Got it for my son, he loves it! Have to remind him not to wear it multiple times a week. Material is very soft feeling, fits true to size and is just a cool looking shirt. Does it come in a mans size?


vestibilità normale, fresca e confortevole. si asciuga in un attimo

Good but theres something to say about it

So the part on the left, it annoys me a little. But I have OCD so thats just me. Overall this is a good t-shirt

Awesome product
