SPEED IS POWER. EvoShield's custom-molding thigh guards were designed with speed in mind. Slide the Shields into any standard girdle for thinner, lighter, yet stronger protection. The ultrathin, lightweight Shields disperse impact and form to the body for maximum mobility. Simply remove the Shields from the foil bag to air activate the custom-molding process. The Gel-to-Shell Technology transforms the soft gel pads into a protective Shield in minutes.
