Features of BCJ-5950
Ninja pocket
The construction of the back buoyancy type BCJ does not permit incorporation of a large side pocket. However, the BCJ-5950 features a large, concealed, detachable inside pocket for added convenience.
Lumbar support system
For reduced back fatigue, lumbar support is provided to the lower back using a stiff material around the waist.
3D type bladder assures greatest buoyancy with compact size.
By adding one additional layer of thickness in the form of a gusset to the previous two-dimensional flat type air bag, a three-dimensional air back has been created and inner volume has been greatly increased. The benefit is a more compact design with greater buoyancy. The BCJ-5950 also uses a 1000 denier nylon for optimum strength and durability. This is a back-buoyancy product for advanced divers.
Advanced Weight Loading System
In the new design, the weight loading system has evolved into a buckle type. Setting weight has become even easier than in conventional products. The construction 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 "weighed-down" feeling traditionally associated with the weight belt is eliminated. Four kilograms (maximum: 6kg) of weight can be placed in each of the left and right sides, and the two service pockets on the rear side of the jacket can each hold up to one kilogram (maximum: 2kg) of additional weight. (Total recommended weight: 10kg; maximum: 16kg.) Naturally, the weight cartridge is easy to release in an emergency, but the safety lock ensures that it is not released accidentally.
Soft pad
Thick cushions are used for the back pads, achieving a comfortable fit.
Waist Support System
The bottom of the shoulder straps can be attached in either of two positions which are appropriate to the conditions of use and the body type of the diver, thus improving the fit.
