We are XX-XY Athletics, a mission-driven apparel brand founded by former gymnastics champion Jennifer Sey. We believe that women’s sports are worth fighting for, so we’ve dedicated ourselves to protecting their integrity and fairness. Our brand champions biological reality by providing high-performance gear for athletes and advocates who believe female-only sports categories are essential. Beyond our premium clothing line, we act as a cultural disruptor and a community hub for those who value truth and fair play. A portion of every purchase you make goes directly to the XX-XY Athletics Fund, which supports organizations and brave athletes fighting for the safety and privacy of women in sports. We pride ourselves on creating high-quality athletic wear grounded in the unapologetic belief that "the truth always fits.
