Meet Shamrock Shirts: Our Story

We're a small family business in the Hawkesbury district of NSW. Like you, we're car people. Always have been. And we started Shamrock Shirts to bring the car scene modern and minimal designs, on really great quality clothing.

Everything we sell is hand-drawn and hand printed to order. We don't outsource any of our design work, or buy pre-printed t-shirts. We're all about quality, ethically made clothing and excellent 'old school' customer service.

What began with Top Gear tees in 2007 has now grown into Australia's largest range of automotive t-shirts. 17 years in business and we're still having fun!
