Contour™ Weighting KitThis weighting kit is designed specifically for the Contour and ContourS Sidemount Systems. A single Contour weighting kit is included in the Contour system. However, if needed, divers can add an optional second set of weight pockets to your Contour Sidemount System. The kit consists of two weight pockets that hold 5 lbs. (2. 3kg) each, and can be mounted to the top or bottom of the Contour underneath the backplate opposite of the supplied weight kit.
