Are waterproof seat covers good for dogs and outdoor gear?

Neoprene-style covers like CAR PASS's get the strongest waterproof reviews across the reviewers we read, with owners citing successful protection against muddy dogs, wet wetsuits, and gym bags. Leatherette covers wipe clean but seams aren't fully sealed, so they're splash-resistant rather than truly waterproof. For heavy pet or outdoor use, neoprene is the consensus pick.
