Using these AltaPRO S Knee Protectors is a breeze. First, adjust the straps to fit your knees comfortably. You can easily put them on and take them off thanks to the Original AltaLOK Easy On/Off locks. When using them, you'll enjoy great traction and support, whether you're in a tactical situation or doing other activities. For maintenance, you can wipe them with a damp cloth to keep them clean. Avoid exposing them to sharp objects as this could damage the Cordura Nylon cover or the foam padding. Store them in a dry place when not in use. Also, make sure to check the brass grommets and straps regularly to ensure they're in good condition. Remember, these knee pads have fasteners on the right side of each pad, so put them on correctly for the best fit.
