You want to protect your knees, but that coverage can't come at the price of the mobility and strength you've worked so hard to develop. The Ion K-Pact Select Knee Pad brings the two needs together with their Tectonic Fit technology, a design that separates the knee and shin panels to ensure the pad maintains the flexibility you need. The pad itself uses lightweight EVA side panels to disperse crushing impact forces without sacrificing mobility in key areas. The knee pad zone features SAS-Tec and Air Prene padding, both of which are used for their flexibility, breathable comfort, and impact protection. Power Aramid material along the upper pad withstands abrasion and tearing forces, should you slide out on your bike over rugged ground.
