Standing, kneeling or prone, protecting your knees is always important in any physical situation. The Vortex Gel-Core Hybrid Knee Pads were created to provide wearers with the utmost comfort. More specifically, they were designed to support individuals engaged in law enforcement and military activities. The “hybrid” comes from combining both high- and low-density materials for ultimate cushion. The GEL foam core contains two shock-absorbing gels that help withstand body weight, which also ups the comfort factor. MSRP $68.
