The Oakley All Mountain D3O Knee Guard offers technical protection and total comfort so you can push your limits with confidence. We designed this knee guard with highly durable Cordura fabric plus D30 in the knee pad, for move-with-you flexibility and patented energy dissipation keeping your knees protected from abrasions and impacts. Plus, we made the All Mountain D3O knee guard with a minimalist, breathable sleeve design with ergonomics built for ease on and off the bike. Finally, elastic webbing and anti-slip silicone make sure this pad stays put, mile after mile.
