Abstract: A protective guard worn to protect the surface of the shoulders from the pressure caused by straps and load of a bag. The protective guard has a shell made of a durable rigid material, shaped and configured for attaching to the upper and rear surfaces of the shoulders and the lower rear neck surface of the wearer. The shell has an inner surface making contact with the surfaces of the wearer and an outer surface making contact with the bag. A pad means is attached to the inner surface at predetermined regions corresponding to the upper and rear surfaces of the shoulders of the wearer. Located on the outer surface of the shell is a means to prevent slippage of the shoulder straps when placed on the shell. There are several means to prevent slippage of the shoulder straps on the shell. One means is a channel defined by a pair of ridges formed on the outer surface of the shell. In the alternative, the means can be a patch of rubbery material attached at predetermined regions.
