By channeling air through a carefully designed sequence of chambers upon impact, RXR claims its Air Shock Absorber technology offers up to eight times the energy absorption of traditional back and chest protectors. Air flows out from the impact and then, directed by the chambers, doubles back on itself, dissipating energy. While this does appear to be a well-constructed, cleverly conceived product, the Morocco-based company offers very little actual evidence of its effectiveness, presenting data that lacks comparison to actual rival products. Nevertheless the ASA protectors are CE approved. Targeted at supercross and motocross competitors, we can only hope that it works as claimed.
