The Ergodyne ProFlex 342 Extra Long Cap Injected Gel Knee Pads are the biggest and baddest beast you can get. They are a monster to the world, but a teddy bear to your knees and tendons. The patented suspension design redirects pressure away from the patella and the 100% injected gel and PU foam make these knee pads unique. The fastening system uses the calf muscle to eliminate straps behind the knee, and the extended shin protection optimizes stability and comfort. The knee pads adjust to any calf size and are sold as a pair.
