UF PRO recently posted an article on the design principles behind their UF PRO Knee Protection System. Utilizing the Richard Davies Axiom – Protection efficiency = Protection level x Surface covered x Time, the US PRO Knee Protection System consists of a flexible and compact protector that is inserted separately into a specially formed knee area of the pants, remaining in the right position without affecting comfort.
