We visited yesterday with Troy Knight of Leatt who among their other products demonstrated the technology behind the Armourgel used in their AirFlex knee pads. Originally used under in US military vehicles to reduce the deadly impact of explosives going off under vehicles, Armourgel absorbs impact as opposed to dispersing impact as do the padding used in most other soft knee pads. Their official description of Armourgel from their website is: "Armourgel, a non Newtonian gel that locks up the molecules and becomes hard on impact." Watch the video below to see how the Armourgel becomes solid on impact. This stuff feels like Play-Doh, but it resists changing shape when Troy hits it (hard!) with a rubber mallet!
Not only does the pad provide great protection and feels cool during wear, Leatt's new pricing of $69 makes the AirFlex pad price competitive with G-Form pads.
