"What is DEFLEXION™ technology?
It sounds like something out of a comic book: a fabric that remains soft and flexible under normal conditions, but can absorb and disperse the shock of impact, protecting against damage and injury. Any superhero would want it, but it's available to all. DEFLEXION™ technology from Dow Corning, a shock absorbing, high performance material, uses silicone technology to create unique impact protection solutions."
