YOU MUST SELECT A MASTIFF DESIGN FROM THE DROPDOWN OR YOU WILL NOT BE ABLE TO ADD THIS ITEM TO YOUR CART. THIS SELECTION IS REQUIRED.

Please double-check everything before checkout. Nobody wants the wrong Mastiff showing up to school on picture day! 😂

One price. Every size. Because everyone deserves to wear their favorite Mastiff

Pre-Order Information

These youth sweatshirts are made to order and will initially run in 1-week pre-order intervals.

I don't keep blank sweatshirts or DTF transfers in stock. Once each pre-order period closes, I order the supplies and personally hand-press the sweatshirts using my commercial heat press after everything arrives.

Orders are completed in the order received. Processing depends on supplier availability and current order volume.

Good merch takes a little time—even when the young Mastiff fans are ready to wear it yesterday!
