@goog Shirtigo is a german service I've used in the past, their quality is pretty good! The only thing I'm not sure about is the size, but everything else they seem like a good match Printify might have good options too, they have the largest catalog by far, but it's really hit or miss since it's a lot of different suppliers/factories For print quality look for DTG (direct to garment) instead of heat transfer Some local print shop might have the equipment too! But it might be expensive if they only do screen printing
