Each shirt is custom-ordered based on the size you requested in your traveler information form when you completed your registration, according to the size chart provided. Because shirts are customized for each tour and traveler, we unfortunately don’t have the ability to exchange these gifts at this time. However, if your shirt does not fit you as desired, please still bring it on the tour and have it with you at dinner on the first night: you may find that other travelers are looking to swap for a different size as well and that you can exchange them amongst yourselves!
