In 2024, Guy launched the K1-B Head Gasket™ Bobble Hat. After years of not having full control over the merchandise, Guy decided to get back to basics and bring it home.
We changed suppliers to a brilliant family-run knitwear business based in the Scottish Borders called Wonky Woolies. Our good friends at Red Torpedo will be helping us with fulfilment going forward.
You can only buy the new Head Gasket™ Bobble Hats here.
We will also feature products that Guy has approved as official merch partners. Please remember, unless you buy it here or from the affiliated links below, it will not be a genuine Guy Martin product.
UPDATE 11th April, 2025
That's it folks, the K1-B Head Gasket™ Bobble Hat has sold out.
Thank you all for the support. We will be back in the autumn with something new!
