Protector case
A pocket stash
Short answer
Small, tough, a pile of meds that isn't a puddle when you die maybe. Persistence still applies.
Also: ammo box · protector
How it works
Protector cases are small containers. Useful. Not magic.
What to do
Meds and a spare mag. Not a museum of stones.
Don't
Don't invent a drop-protection chart.
