Velcro®-backed vertical straps are adjustable and allow positioning of SPMM™ modules anywhere on the vertical brace. 3 support struts in the rear for extra support of heavy tools. Heavy duty engineered dorsal yoke distributes weight evenly and vertically rather than a simple criss-cross design that strains shoulder and neck muscles. Adjustable chest belt eliminates shoulder creep and allows an unbuckled belt without losing tool load. Extra wide padded shoulder pads are integrated in-place and won't slide out of position. Non-metal integrated suspender terminals will never snap free of belt regardless of weight carried. Replaceable suspender terminals. Integrated yoke hook allows easy storage and retrieval. 2 inch nylon Velcro® 3-strut black suspenders with interchangeable ends.
