So I got my new BG chest entry 4/3 and am loving it. But the key stash is different than my old situation. There is like a small elastic loop in the exterior chest, then you pull the flap over the head and zip it over where the loop lives. If the key isn't secured well, it will simply wash out of the side of the flap that was pulled over the head.
How do you secure the key with this elastic loop? All I csn think of is to thread floss through the key and tie it to the loop.
Pull the elastic through the hole in the key
Open the elastic to create a loop, pull key through the loop and pull on the key to tighten.
Then it's locked in and will never get loose without a hand opening the loop
