rainproof

Won't let through

Rainproof means resistant to rain—not necessarily waterproof, but able to shed or block ordinary rainfall.

A rainproof jacket keeps you dry in a drizzle; a rainproof tent holds up in a shower.

As a verb, to rainproof something is to treat it for rain resistance: We rainproofed the deck furniture before storm season.
