The ION K-Pact AMP HD Knee Pads are the top-tier version of the brand's classic protection for progressive downhill and freeride mountain biking. Power Slide caps on the knee enhance durability with the ION Pad K-L2 LONG padding extending further down the shin for heavy-impact protection. We also like the comfort of the angular cut, pre-shaped ergonomic fit, and Ergo Strap above the calf muscle for a custom fit.
