Born from founder Yin’s own experience of feeling out of place in the boxing gym, KoStudio.co designs women’s boxing gloves and training gear around female proportions rather than shrinking down men’s equipment. Its in-house designs are tested with real fighters, design consultants, and gender-ergonomic experts, pairing wrist-supportive function with expressive styles and a community built to help women feel at home in the sport. More than 8,000 women have chosen to train with KO over generic boxing brands.
