Option 1 — Main Design on Front: Your selected Mastiff design is printed large on the front. Nothing is printed on the back.

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.

Double-check your selections before checkout. We want your favorite Mastiff, not an unexpected guest appearance! 😂

All sweatshirts are unisex. Please refer to the size chart poster image for measurements before ordering.

Pre-Order Information

These 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. After each pre-order closes, I order the supplies and personally hand-press your sweatshirt using my commercial heat press once everything arrives.

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

Awesome merch takes a little time. The Mastiffs aren't exactly known for waiting patiently, either!
