Fine nylon mesh repels water- just like a nylon bag or jacket. It doesn't work so well if the material is drenched or submerged, but splashes of water will just bead up & roll off.

I wouldn't like to wrap an esc too tightly in an outerwears cover as that will restrict airflow somewhat- the kid whom killed his Flux esc had wrapped his esc in an outerwears, geared for 100mph, was running 6s lipo & was also running massive 40 series Big Joe tires = perfect way to fry any esc really...
