The present invention includes at least one knee pad and an associated method of attaching work quality external kneepads onto work pants by an attachment fastener. The attachment fastener preferably includes a commercial quality hook and loop fastener. The present invention adapts a pair of conventional work trousers to accept, when needed, conventional padded knee protectors. By using hook and loop fasteners, the kneepads can be quickly and simply attached and detached without having uncomfortable straps around the leg and therefore overcomes prior art shortcomings of hindering blood circulation. Thus, the direct attachment to the pants in lieu of straps means that there are no straps to cut into legs or cut off circulation. An additional benefit to this system is the convenience of laundering the work clothes.
