You leave the house, and It's a beautiful day, all bright and sunny. Then - before you know it, a gloomy cloud parks above and unloads. Well, thankfully you wore your Rain-belt!
This ordinary looking belt, has a thin, waterproof raincoat tucked into the zipable comparment that goes right the away
round the belt.
Just take shelter when it starts pouring, pull it out, put it on, and do as you please.
When you're done using it, you let it dry, then roll it up, shove it back in the belt, zip up, and you're locked and loaded for round 2.
