The bottom increases the ten thousand anti skid grain to match the clasp, the security does slip. The design of elastic fastener buckle is more suitable and safer. Anti-bacterial Lycra: not easy to breed bacteria in water and sweat. Our airbag cushion is constructed using durable and tear-resistant materials to ensure its longevity. JFT air cushion products adopt air convection patented technology, when the air bag pressure when the gas flow to each other uniform pressure to produce "anti-gravity" effect, can buffer the external pressure, to achieve the effect of dispersed pressure, shallow hollow design, enhance the ventilation, pressure relief effect.With patents, authorized certification, quality assured.Eleven 3D convection air bag design is adopted on the surface to fill the air flow chamber. During use, the bearing part is in direct contact with the air flow chamber to generate even anti-gravity, so as to disperse the pressure and make cycling more relaxed and pleasant. The high-pressure airbag acts as a cushion, absorbing the impact force during a collision and significantly reducing the risk of severe injuries.
