Hi @Michel - Thanks for your patience while waiting on correct info and for catching that sizing discrepancy! For head circumferences with this hat, the large is 59 cm and the XL is 61.5 cm. Looks like the XL will be the right fit for you. You can also see the product page for the REI Co-op Vented Explorer with updated sizing. Thanks again for working with us on this one!

At REI, we believe time outside is fundamental to a life well lived.
