A new Integrated Stabilizing Harness has been developed for the BCJ-6900. In order to reduce the weight, the previous long rail type Ultimate Stabilizing Harness has been redesigned into a more compact size. Of course, the superior concept of the Ultimate Stabilizing Harness remains the same, with two rails firmly securing the tank. The harness is compact and yet tightly holds the tank, preventing it from slippping or shaking whether in the sea or on land.

By adding extremely expandable spandex and a 3-D air cell, inner volume has been greatly increased. The benefit is a more compact design with greater buoyancy. Also, the BCJ-6900 uses a 840 denier nylon for optimum strength and durability

Thick, solid cushions are used for the back pads, achieving a comfortable fit.

The Advanced Weight Loading System allows the diver to insert weights into the weight cartridges as well as into the loading pockets on the front of the jacket. Additionally, with weight distribution to the shoulder area, the uncomfortable feeling that is traditionally associated with weight belt is eliminated. 8lbs of weight can be placed in each of the sides, and the two service pockets on the rear of the jacket can each hold up to 2lbs. Naturally, the weight cartridge is easy to release in an emergency, but the safety lock makes sure it is not released accidentally.
