How to use: Put on the knee guards just like you would put on any regular knee - wear. Wrap them around your knees and adjust the calf tension band to make sure they fit snugly. This will keep them in place while you're riding. Things to note: Make sure the D3O inserts are properly placed inside the Cordura® fabric. Don't wear them if the skid plates are damaged as it may affect the protection. Maintenance: You can clean the guards with a mild soap and water. Let them air - dry. Don't put them in the dryer as it may damage the materials. Check the skid plates and D3O inserts regularly for any signs of wear and tear. If you notice significant damage, it's time to replace the guards.
