As a member of Decathlon, you have 365 days to return or exchange your purchase. If you'd like to return for an exchange (on any product across our website), we'll send you a free-postage label so you can send us the product back. Meanwhile, we'll place a new order and send you what you need in exchange. If you are unhappy with a product and wish to upgrade to the next model above, this is completely fine, you will just have to cover the cost difference. In case you'd like to return for a refund, you can return the product(s) either through AU post or Parcelpoint and we'll refund the price of the product to you as soon as your return is on its way to us. Refunds take 1-3 business days to reach you. We're here to help!
