haha, yep, and i use that exact one, too. just leave the keys and stuff on it while i climb. verizon gives us climbing-grade ones, too.

i clip it to the edge of my pocket so i dont have to go digging down to the bottom to get my keys. and it also helps secure them. i have a complex about making sure i have all my stuff. i often check the '4 corners' to make sure i have everything. front left is keys, right right is phone, back left is knife and back right is wallet.
