Hi Janet, thank you so much for choosing us for your grandson’s Christmas gift! We are thrilled to hear you love the quality of the lettering.
To put your mind at ease regarding the care: we include washing instructions with every order. Because both layers of the Greek letters are securely sewn onto the garment, they are incredibly durable—the letters themselves will likely outlast the sweatshirt! They can also be safely ironed or dry cleaned. We hope the Large fits him perfectly and that he loves the hoodie!
