This head-mounted boxing reaction ball targets boxing enthusiasts. It boosts reaction speed, punching accuracy, and hand-eye coordination, so it serves as practical gear for daily or home training. The set consists of an adjustable headband, a training soft ball, and an elastic cord, with two color choices, a knitted headband paired with either a red or a black soft ball. The headband uses adhesive Velcro and elastic nylon. It fits various head sizes via free adjustments, and its professional D-ring buckle ensures better durability and stability than non-adjustable alternatives. The soft ball has a golf-style textured surface with moderate elasticity-it feels comfortable to strike, lowers hand injury risks, and rebounds flexibly with each punch to mimic real training.
