At 13 Under, we’ve done things differently to make sizing simple and stress-free. Unlike many golf brands that use generic sizing like small, medium, or large, we’ve chosen traditional dress sizing.

So, if you normally wear an Australian size 8, you can confidently order a size 8 from us—it’s that easy!

For our international customers, we’ve included a size conversion guide (here) to help you find the perfect Aussie size equivalent. If you’re still unsure or have any questions, feel free to reach out—we’re always here to help!

We get it—ordering the wrong size can be frustrating. That’s why we’re happy to offer returns for an exchange or refund to make things right. You can find all the details about our return process here. If you need any help, don’t hesitate to reach out—we’re always here to assist!

We know you’re excited to receive your order, and we work hard to get it to you quickly! All orders are dispatched from our Sydney warehouse within 1-2 working days, so your new gear will be on its way to you in no time.
