Size guide
Tees
Comfort Colors 1717 runs relaxed. The easiest way to pick: lay your favorite tee flat, measure straight across the chest from armpit to armpit, and match it to the chest width listed under Details on the product page.
Want it roomy like a band tee? Go one size up.
Hats
Wrap a soft tape around your head about an inch above your eyebrows and just above your ears, snug enough to slide one finger under. Compare that number to the fit range on the hat's product page. Between sizes? Go up.
