The Engine: 

Hand-picked factories with safe, fair, legal and humane working conditions.

Different products have different sources of origin. Most of the premium shirts are AS Colour based, who seek out the best factories in each specialty. They may interview up to fifty factories before selecting one to make their products. Each factory is based on a certain fabric and an assured production capacity. All factories get a regular order every six weeks, giving them certainty around work and income. They choose to work closely with fewer factories that are known well. Importantly, all AS Colour's products are produced under safe, fair, legal and humane working conditions throughout their supply chain.


Engine Maintenance:

To gain maximum mileage, it is recommended that you machine cold wash with like colours, do not bleach, and line dry in the shade. Do not iron, dry clean or tumble dry. A bit like Stirling Moss I push my engines hard, so I have been known to iron these t shirts inside out.



I want a t-shirt but you don't have my size. What can I do?

I am in initial race mode, so I’m developing new lines, further sizes as I go, as well as figuring out what is going to work best. Please can send me an email at with a request for size and the style you would like, and I will see what I can do. Hearing from you allows me to adapt and provide a better range.

For out of stock items, I rely on wholesalers and printers and can often not provide an exact date. If you would like to be the first to know when an item is restocked, simply open the page of the tee you would like, select your size, and click the green "email when available" tab. We will send you an email as soon as it is back on the race track. 

Do you have womens or childrens sizes available?

Many of the T Shirt designs are unisex. I don't yet have children's sizes however  please drop me a line at as I should be able to create a custom product for you.

I entered the wrong delivery address when I placed my order! What can I do?

Email me at with your order number as soon as possible and I can change your delivery address if the item has not yet been sent to the couriers.

How can I return my order?

Please assume due to each item being custom printed after you order, that returns are not possible, so please check the sizing guide carefully.

I love my tee but it's too small/large. Can I exchange it?

We do not offer straight exchanges at this time.

I’m not exactly sure what size to purchase?

Sizing instructions are on the website. If in doubt its probably better to go up a size than down a order larger.

Do you ship internationally?

Yes we deliver internationally.

Delivery is taking a while to arrive?

All items are custom made after your order is placed, and shipped from that location to reduce costs. They can take up to a week to be made, before they are sent to the shipping company.
