Lightweight, soft, and built for movement — this youth tee carries a bold, vintage dojo vibe without slowing down play. The circular “Ground Rules Academy” emblem wraps around stylized kanji, giving it a practiced, slightly worn look that reads like a team patch. It sits cleanly on the chest so kids can train, tumble, or hang out after class while still looking put together. Breathable airlume-combed cotton and a retail crew neck keep the fit modern and comfortable. Whether it’s for belt-testing day, after-school practice, or casual wear, this shirt feels familiar and resilient — like the first layer of a young athlete’s uniform of confidence.
