The landmark tees in the HawaiiGuide Store each wear the same hand-drawn stamp you can collect for free in the HawaiiGuide Passport. Hike Diamond Head, tap the stamp on your phone, then pull the matching shirt over your head. That's the whole loop.
The Passport is a free digital passport that lives on your phone and lets you stamp the landmarks, beaches, waterfalls, and local grinds you actually experience on the islands. No account, no app download, no cost. You stand at the Kalalau Lookout, tap "I've Been Here," and the hand-drawn Kalalau stamp inks into your passport with the date.
The stamps are the part people fell for. Each one is a circular, engraving-style illustration of the landmark itself: Diamond Head over the Waikīkī shoreline, the Hāna Highway winding along the cliffs, Waimea Canyon's ridgelines, all drawn in the island's own color. Orange for Oʻahu, blue for Maui, red for the Big Island, green for Kauaʻi.
So we put them on shirts.
