You'll lose it before you break it.
- Gender: Male
- Familiarity: I've put it through the wringer
These are the standard. Can't go wrong. I've never seen one break, although I seem to lose one of these out of carelessness every few months.
PRO TIP: put a headlamp in one, seal it, and send it floating down a 300 ft. waterfall at night. Then have a fetching contest with your buddies at the base in the river. Good time.
