Very happy with our hats. We have had them before. Once through WCI club and another through Cancer Foundation Shop. The 2 we got this time are even a better design. Thanks again for the prompt delivery. Thankyou Dawn and Lawrie

Great Product and Service

We have purchased several of the Helmet Hats and find that they are a great product. PLUS, they stand by their product even several years after the purchase date.

Treadley Explorer Hat does the job

Delighted with our SunBrim Treadley Explorer hats. They fit perfectly over our bike helmets meaning we can protect ourselves from the sun while out and about on our bikes.
