You will have 14 days from receiving your order to report any issues such as damage or defects to the outer packaging or missing or damaged items within your order. We will not be held responsible for any issues reported after this period. When reporting these to us please ensure you have photographed the issue as we will ask for this to conduct our investigation.

To report any issues with your order, please email with photos of the issue for reference.



 Unfortunately, once the order has been placed we can't change the order.

This includes the following:

  • Changing the item/ size
  • Delivery/ billing address
  • Adding other items to your order
  • Shipping address/ method

We're pretty quick at picking and packing your order, therefore we need to be quick to cancel your order once your purchase has been confirmed. If you contact customer service straight away we may be able to help. After it has been processed, cancellations will follow the usual returns procedure.



If you are not satisfied with your purchase, you have 30 days to return a product for refund.

If you request a refund of the original purchase price, this will be issued back to the original payment method (excluding the original postage that has been paid).

Refunds will be issued if items are returned in their original unworn condition with original labels attached. Returns that are damaged, soiled, scented, worn or altered will not be accepted and could be sent back to you. In the case that an item is deemed faulty and a fault of Gym King we will also refund your postage. 

Abuse of returns policy, such as repeat refunds with no valid reason, free wardrobing & chargeback fraud will not be accepted. Gym King reserves the right to make the final decision on refunds and returns. 




Don't worry, we've most likely got your parcel but it is waiting in processing. Due to high volumes, we are unable to notify you we've received your returned parcel. Please keep hold of your proof of postage receipt. Once we've processed your return, you will receive a email and SMS notification. Please allow us up to working 14 days to process this.
