I have a backpack that uses MOLLE webbing and a closed loop, similar to the one pictured, for the chest strap but I broke it. I’ve tried searching for terms like MOLLE webbing hooked loop and what not but can’t seem to find just the loop. The item pictured was for a strap you can use to compress bags and they seem to be mostly available in packs. I’ve just been using a carabinier in the meantime.
