Go big, confidently. The Drop In D30 Knee Gaurd is your durable, abrasion-resisting, super-breathable knee guard that keeps you comfy and protected at every turn, jump, and drop. This downhill-focused knee guard is moto-grade certified, so you can take on the descent like a pro. We made the Drop In D3O with highly durable Cordura fabric to protect your skin, and created the removable knee pad with impact-absorbing D30 and lateral, 3mm EVA foam. Comfort's still front and center: ergonomic design feels just right on and off the bike, while ventilated stretch mesh keeps you cool where it counts. Finally, we added adjustable velcro straps on the top and bottom of the knee sleeve for a customized, stay-put fit every single ride. From big-mountain rides to your local hills, this knee guard lets you push your limits, more safely.
