Shred science.

If you ride, you'll crash, and if you crash, you'll tear up your knees, unless you rock the Leatt Airflex Knee Guard on your 'caps. The Airflex is one of the lightest knee guards out there, at under four ounces per, and it features MoistureCool wicking and breathable fabric to keep sweat from building up. Even better, its non-Newtonian Armorgel padding is soft and flexible until impact, upon which it hardens instantly to keep your knees from splitting open on rocks or getting torn up by gravel, so you don't have to pedal home with blood dripping into your socks.
