The Pro-X3 Bike Short Liner have been created to be worn below baggy mountain bike shorts and provide protection without standing out. Made from a lightweight material that works hard to wick away moisture when you are hard at work. The design also includes a built-in seat pad and a handy leg pocket for storing small essentials.
These liner shorts feature SmartFlex™ to give you highly flexible protection, that will not restrict movement. The design allows for complete freedom of movement and enables you to manoeuvre across any terrain without feeling restricted. In the event of impact, this flexible material hardens, soaking up the force to boost safety and protection.
