This HAYASHI super lightweight shin guard is made of 100% polyester mesh for high elasticity. The front protector is made of compressed EVA foam, which can absorb high impact energy and prevent overstressing of the periosteum and musculature (avoidance of shin splints!). The mesh fabric is breathable and supports the calf muscles with its fine tissue structure. This improves circulation and oxygenation in the legs. The two hook and loop straps support a firm hold of the protectors, without affecting the wearing comfort thanks to the soft mesh fabric.
