The Spiritus Systems Fat Strap Mk4 is a universal H-harness designed for use with the Micro Fight Chassis, 34A Split Chest Rig, and Thing 3 expansion chassis. The Mk4 version features a reduced-profile construction with an updated nylon laminate overlay that provides additional horizontal mounting points for PTTs, cable routing, and mission-critical accessories. Integrated shock-cord holes allow further modular expansion.
A rear loop field allows placement of name tapes, IR markers, or unit identifiers.
Only one Fat Strap Mk4 is required for a complete harness setup.
