The blood group patch is an important element of every fighter's equipment. Information about the blood group will greatly facilitate the work of doctors or paramedics in the case of providing emergency care. The patch is made of high-quality PVC (polyvinyl chloride) thanks to which it is elastic, flexible and weather resistance. The oval-shaped patch with rounded edges is conveniently attached to the Molle interface of the equipment. Such a patch will inform medics about your blood group and help save lives in a critical situation.
