None is lighter, smaller stowable and more comfortable than the Pro-X3 Knee Guard by G-Form. The soft, elastic Smartflex foam is sewn onto a fine Lycra stocking and underlaid with a soft EVA foam. Thus, the G-Form Pro-X3 Guards around the knee almost like a second skin and allow hours of riding without disturbing. The G-Form protectors are ventilated and therefore much less sweaty than conventional protectors, but still protect the knees effectively from drafts. As there is hardly any weight and thanks to the rubberized finishes, the G-Form protectors hardly slip. The Pro-X3 Knee Guard is available in six different sizes, so one is sure to fit perfectly. The Pro-X3 Knee Guards are recommended for CC to Enduro, Park and 4X use. The Smartflex polymer foam is only 10mm thick and hardens within milliseconds of an impact, absorbing up to 90% of the energy. Afterwards, the foam immediately becomes soft and supple again. The waterproof pads seal foam eroding sweat and the Pro-X3 can be washed at 40 °.
