Rugby is a collision sport where every tackle leaves a mark, yet breast impacts in women’s rugby are often hidden by shame and a lack of awareness about injury. To ease the burden of having to report an injury alone, Castore introduces The Impact Report: Uniform. When the chest area of the uniform receives a force of 300N or more, spiropyran technology turns it deep red. It is not a diagnosis, but a signal that allows coaches and medical staff to approach the player first and begin a conversation, while the player remains in control of her own story. Heat from washing and drying returns the uniform to its colourless state. Launching with the Red Roses, the idea will extend to the public through multiple media channels and OOH. Through #THE_IMPACT_REPORT_UNIFORM and #EVERY_HIT_LEAVES_A_MARK, Castore will make clear that breast injuries are sports injuries, too.
