The buckle strap is a simple buckle and strap assembly that can be added to newer FHF pouches allowing you to switch between the silent bungee and hook closure and a more secure buckle closure. A set of them would also allow you to easily hang a MOLLE Muff from the bottom of your Bino Harness or Fishing Rig if equipped with bottom hanger loops.
Buy a single strap (1) ($9) for one pouch, or a set of two ($15) for multiple pouches or the MOLLE Muff (attachment to bino harness).
