How to waterproof your clothes

Colored beads of water on a flat surface

WaterBeader's a superhydrophobic coating that causes liquid to mesmerizingly bead off of whatever it's been applied to, a significantly cheaper option than similar products out there, that also doesn't require a two-solution bottom/top coat. Plus, it comes in a convenient aerosol spray, which makes it far easier to apply evenly to clothes and kicks, and shockingly easy to sneak-waterproof people's hair.
