I've loaded the basics here on your webstore for easy ordering. If you're not sure of sizing, then I'm happy to connect with you for a try-on before you order. Also, check with some of the other guys on size, since many/most of the veteran members have shirts.
If you're not sure of hat size, then text me at 440-963-5424 and I'll grab you a try-on cap. We have New Era and Flex-Fit brand setup for you. Two great brands! New Era is offered in some SUPER COOL styles and colors too.
Don't forget...I'm always happy to answer questions. Val
