Everyone will think it's a palm tree. It isn't. Sigillaria was a towering, spore-bearing giant that dominated Earth's coal swamps over 300 million years ago - before the dinosaurs, before the continents split, in a world that barely resembles our own. It grew up to 30 meters tall from a single, unbranching trunk. Not just some random tree. This one was here long before the palms. Ancient forests made from trees like this one reshaped Earth's atmosphere and set the stage for almost everything that came after. Embroidered on a lightweight five-panel cap with a flat peak, adjustable metal clasp, internal mesh support, and tonal under-peak lining. Structured enough to hold its shape, soft enough to forget you're wearing it. One of our most-reached-for pieces.
