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.

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

Refunds will be processed within 10 working days from the time of receiving your item(s).

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.
