Oahu is a lot of things to a lot of people and most of them are right. The shirt wears that tension well: O'ahu in distressed retro athletic lettering arched wide across the chest, with Hawai'i in a worn block stamp underneath, the whole thing looking like it's been through something and came out fine.
For people who grew up here, moved here, or left and never fully got over it. The men/unisex cut is slightly slim, long sleeve and kids versions are regular fit. Available in black, heather gray, Kelly green, and turquoise. Makes a genuine gift for anyone the island claimed, and a souvenir that actually means something.
