Who makes it

Our spirit. Our hand.

Two things go into every piece before it ships: why it exists, and who makes it.

Our Spirit

Our Spirit

Born on the court, not in a boardroom. We're players first. Every piece is cut for a real match, then judged by whether it still looks right at dinner.

Our Hand

Cut and sewn in Vietnam, where performance knits are a specialty. Every seam, collar and placket is built to hold its shape. Our wash-test results go on the craft page as they come in.
