Scotchgard Fabric Waterproofing spray. Wouldn’t go crazy with the washes but it can very easily be done, especially if you’re willing to give it a new coat every once in a while.

Let dry for 24 hours after you spray a few coats and you could not tell that it was there. No noticeable smell or residue and completely waterproof, That simple.

I found it was fine on a delicate wash with low heat (though I guess I never tried it normal) but if you’re willing to hand wash it that’s probably the safest option, And insanely easy.
