Securing belongings when out and about ?

[ukran1ans]

I actually use a water proof cell phone cover and I have cargo pockets (closed by velcro) in all my swim trunks so that I can carry my day's supply of funds on the beach.

At night, again, my shorts have cargo pockets to keep at least half my cash for the night secure, never carry a wallet and have all money/credit cards in front pockets...
