Much like the elusive 'neverwet', but these ones repel everything including low viscosity fluids like ethanol.

The other main upside to these is that the water actually bounces off. I have found current superhydrophobic sprays leave water drops which eventually wet out the material.

Probably a couple of years away though.

We're on the precipice.

We're all spacemen compared to the wool and waxed canvas of the 1970's, but in a decade we'll be measuring our clothing's weight in tenths of an ounce and "wetting out" will be something that only happens to old codgers who never upgrade their gear.

Rain? Gross. Who likes wet clothes.

In the REAL future our robots will backpack for us.
