A device for coupling a limb guard to a human limb includes a support sleeve configured to wrap around the limb. The support sleeve includes a friction pad configured to cushion the limb and oppose translational and rotational displacement of the device relative to the limb. The support sleeve provides a stable attachment surface for a joint guard and/or limb guard and may be worn without discomfort for extended periods, remaining stationary relative to the limb while a person wearing the device moves about.
