OG tennis brand Boast is officially back in play. Famous for its polo shirts, a collaborative project with Ebbets Field Flannels expands their repertoire. There are four wool caps to choose from featuring felt patches including the brand’s sometimes misinterpreted logo. And if you have to ask, it’s a Japanese maple leaf—not that other sticky green that’s on your mind. The caps will be available for pre-order starting September. Visit the Boast website for more info.
