The Rugged 2 Knee Guards are all-mountain, enduro and slopestyle-ready guards which feature body-mapped Smart Flex pads, a flexible pad during pedaling that hardens upon impact, absorbing energy from a crash. An outer Dura Tx layer adds durability to the pads themselves, giving you additional peace of mind that these pads will hold up over long term abuse. Extra wide top grippers keep the guards in place, while a ventilated mesh back improves airflow during hot rides. The double-knit compression fabric adds comfort without being restrictive and reinforced seams keep the guards from shredding while you shred out on the trails.
