Adopting multiple air convection technology, when the air bag is bearing, the air flow will produce uniform compression"anti-gravity" effect, which can buffer the pressure of foreign objects hitting the body. Use manual press mode to adjust the air bag, portable and convenient.Slow shock and impact protection Ventilation and heat dissipation. Refreshing heat dissipation. The height of each air bag is about 2mm, and the shallow groove between the air bags enhances ventilation allowing heat dissipation and ventilation between the body and clothes. After the national authority certification, quality assurance.TPU+ high elastic Lycra fabric Environmentally friendly skin breathable can be repeatedly cleaned. 1. Air flow filling, soft support. 2. Environmentally friendly skin, breathable heat dissipation. 3. Very elastic and resistant to deformation.
