Never leave home without one. I’m always amazed others don’t do it as well.

I carry a 5.11 Rush 72. Uually there’s:

• a camera; Fuji X-S20
• contact lens cleaner and storage
• small bicycle pump
• 2 sunglasses (Oakley M2 & Ray-Ban Wayfarer)
• sunscreen during summer
• floppy boonie hat during summer
• one/two pocket knives
• a single watch storage case, usually with a watch in it
• a strip of blood pressure medication
• two powdered ibuprofen painkillers
• a bandaid or two
• a pen

And there’s bound to be something like a roll of candy, a snack, a water bottle, etc in it at any given time.
