A key component of the VHS 4.0 shoulder system is its spider harness. All four points of the spider harness can pivot independently and are connected by our clover shaped, trademarked Flexalon swivel back plate. The 2.75″ wide harness straps on the VHS 4.0 have been recontoured to enhance both comfort and concealment. The VHS 4.0 features Galco’s improved key-hole harness fastener system that replaces the earlier screw-and-post system, resulting in greater security, ease of assembly and greatly reduced chance of fastener loss. The VHS 4.0’s tie-down system that is simple to use, compact, concealable, fully ambidextrous and comes complete with vertical holster, harness, ammo carrier, tie-downs and a set of harness fasteners.
