Answer:
Rain jackets are coated in durable water-repellant (DWR) finish, a hydrophobic glaze that allows the coats to be breathable, yet waterproof. It lets water vapor—like sweat—out, but keeps rain from getting in.

When water molecules come in contact with other surface, the molecules are attracted to the molecules of that surface. In case of rain coat, it is obvious that cohesive force in water molecules is much stronger as compared to adhesive force, so water does not stick to the raincoat surface.
Rain jackets are also coated in durable water-repellant (DWR) finish, a hydrophobic glaze that allows the coats to be breathable, yet waterproof.
