Simply lay a t-shirt you already have on a flat surface, and measure across the front from armpit to armpit.  Then compare that number to our sizing chart.

Nope. We use commercial grade heat transfer vinyl for our t-shirts. This gives you a detailed design with clear crisp lines and won't fade or crack like screen printing does.

We specialise in t-shirts for car guys. But, because we print everything by hand in-house, we'd be happy to print you women's or kid's tees by special order.

We use AS Colour apparel for our base products. They are simply the best quality clothing available, with consistent sizing made for the Australian marketplace.


Regular shipping is FREE. Express Post is an option at checkout for a small fee.

We accept Visa, Mastercard, American Express, Paypal and Afterpay. Direct Deposit payments can be arranged on request, please contact us for more details.

Because we hand print your clothing to order, we need a little time to do this. Our t-shirts are generally printed and sent within 3 or 4 business days.  If you're in a rush, just let us know as soon as you've ordered and we will make sure to work extra hard getting your order out quickly.

All orders are sent with Australia Post and you have the option to choose Regular Mail or Express Post at checkout.

No problem! You can return your shirt to us and exchange it for another size, or request a refund.

We are an online store and don't have a pick up facility. Shipping is free to save you the trip!
