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.
