“Big Ounce” Muscle Tee – Flex for the Ranch King
Sun’s out, Ounce’s out. This Big Ounce Muscle Tee is built for maximum airflow and maximum attitude — perfect for feeding time, fence fixing, or just flexing your oddly specific rodent fandom.
Made from soft, breathable cotton with wide armholes and a relaxed fit, it's as tough and chill as the chunky outlaw himself. Ranch-tested, Ounce-approved.
Sleeves off. Chaos on. Long live the Chonk.
