Bubble showed up a few weeks ago... 5k+ ft elevation swings, and in/out of the truck a few times a week (70°F+ temp changes) rekt it.
Gap gauge comes in handy, used it last week... truck and trailer keys on there as well. Usually stow my everyday keychain in the truck, then use that key to lock the doors.
Whole thing clips to a snap stitched inside the pocket of my jacket.
Map of the area I'm riding, along with my avalanche fieldbook, small notepad, and pens/pencils/sharpie go in my pack.
GPS is mounted to my sled/bike.
