How much does delivery cost?

Delivery cost is based on proximity to Ireland, which is where our products ship from, and will be automatically calculated at checkout. Cost and time varies depending on your selected service. You can find more info here.

Your order will be dispatched within our normal timeframe, however the postal operators around the world can process mail slower than usual, so please, do allow more time for delivery. As previously advised by the World Health Organisation, coronaviruses do not survive for long on objects. It is therefore 100% safe to receive postal items! We thank you for your loyalty and understanding despite these unfortunate circumstances for everyone.

What is your refund policy?

You can find that here.

What is the best way to take care of my new Coffee&Kimuras products?

Our "tight" products are made from a blend of polyester and spandex. We have gone through numerous samples of different materials, testing them ourselves on the mats to bring you the best product possible. In order to maximise the lifetime of your C&K products, we recommend:

  1. Avoiding velcro. Velcro can cause piling, which is essentially pulling the polyester fibres out of the product, significantly reducing the look, feel and lifetime of your product. Do not wash your rashguard or spats alongside shorts with velcro closures. Our Signature Grappling Shorts have a type of velcro closure that is a little more polyester-friendly, but we still recommend washing separately.
  2. Washing inside a delicates net will help reduce the impact of your washing machine drum on the product fibres.
  3. Loose threads can appear through use on the mats. Snip off to prevent damage from multiplying.
  4. Our products include a care label but, as a general rule, wash on low temperature (~30°) with like colours and allow to hang dry away from sunlight and direct heat.

I have a cool idea for a rashguard, can I submit it?

Yes, of course! The only way to progress in Jiu Jitsu is through collaboration. We are open to collaborating with our loyal customers on bringing their idea and design to life. Send an email to with your idea and some background to you. We look forward to seeing your designs!
