The trousers are targeted towards disabled athletes, some of whom cannot detect pain and injury in their legs. The trousers are made of a breathable Lycra fabric which is lined with strips of [pressure-reactive film](https://www.trendhunter.com/trends/mij-technology). The film is situated in pockets strategically placed over the thorax, pelvis and leg bone areas. Upon hard impact, the film releases a magenta dye from micro-capsules that are embedded within it. The amount of dye released is directly proportional to the strength of the impact.
