This vest is most suitable for lighter weight and shorter time use, where the whole jib weight factor is in the 15 - 25 lb. range. The lower straps fasten to a crossbar on the lower front section. The jib arm support fitting may be worn at waist or at chest level. This model is preferred for maximum comfort and is typically used when it is to be worn for hours at a stretch and when the jib arm is at a greater length, where the arm will weigh up to a maximum of 34 lbs. Both vests are tested to and rated at 160 lbs.
All foam is replaceable because of zippers in the construction.
Inner shells are rip stop nylon. Outer shells are 1000 denier nylon. A bubble level sits flush on the upper bowl surface. They feed over the end of the rear tube and position behind the rear pan control unit. The optional crossbar locks with a split collar and two tee bolts to the rear of the main tube and enables fast addition or removal of weight.
