I use 1/8 bungee cord with it girth hitched around one of the molle loops on the saddle. Just run the open loop of the bungee cord around the button as in the above pic. I like the bungee as it is forgiving, and when you make the loop the correct size (you only need a very small piece) it stays on the button even if you bump the stick on a climb. Equally, if you catch the stick on the tree or a limb, the bungee is forgiving. 1/8" bungee material is very inexpensive...Amazon. Good Luck!
