AirCell Core Technology and Products:

Air exhibits ideal physical properties for absorbing impact and shock. We applied air when developing Air Cell technology.

By trapping air with specialized materials that offer flexibility and cushion, our technology delivers optimum comfort and lasting performance.

Each Air Cell is completely separate from its adjoining cell, ensuring the strap remains fully functional in the event that a single cell is punctured.

The durable performance and aesthetic appearance of the finest quality Lycra provides the ultimate finish for the patented Air Cell system.

Material: polyester net and sponge combined.
