Country of origin: Vietnam Quality: Nylon, Polyurethane -Uses XRD® that cures the moment it receives an impact. -Good breathability and supple stretch nylon mesh material cut back to reduce stuffiness. -NEW material with excellent viscosity (stickiness): By adopting TPE x POE, it fits strongly to the movement of the body. ・ Excellent fit due to elastic fabric Uses XRD® that cures the moment it receives an impact. NEW material with excellent viscosity (stickiness): By adopting TPE x POE, it fits strongly to the movement of the body. Of course, it is lightweight and flexible. Since the repulsive force has been improved compared to the conventional model, the "sag" of the pad due to aging is also reduced. The "stretch nylon mesh" is cut back to reduce stuffiness such as sweat during exercise.
