A kneepad comprises a base defining an interior side and a sizing piece attached to the interior side of the base. Moving the sizing piece relative to the base determines the size of a knee that can be accommodated by the kneepad. To accommodate a large knee, the sizing piece may be rotated away from the center of the interior side of the base. To accommodate a small knee, the sizing piece may be rotated towards the center of the interior side of the base.
