Fox Enduro Pro Knee GuardsThe Fox Enduro Pro Knee Guards are premium knee guards designed for flexibility while maintaining impact protection. Made with Micro-Lycra sleeve and abraision-resistant panels panels, the Enduro Pro Knee Guards are both breathable, moisture-wicking and durable. At the heart of the guards is a custom-molded D3O impact-absorbing foam insert, which stays flexible while you are riding and hardens upon impact for the best of both worlds. The Enduro Pro Knee Guards have a slip-on fit, but do include a rear elastic hook-and-loop strap so you can get the perfect fit. Lastly, fitted elastic cuffs and silicone grippers ensure the knee guards won't slip down when you are riding. After a long day of riding, just pop out the D3O inserts and wash the knee guard to keep it smelling fresh.
