The Weathertech visors extend all the way down to the window sill. They work fine in the rain, so long as the window isn't open lower than the visor edge, maybe an inch. (I took a picture but can't figure out how to get it from my phone to my computer.)The front windows were barely cracked and water dripped in while driving. The problem with these are that they're tapered as the visors goes down the A-pillar towards the side mirrors, thus leaving an open gap for water to trickle in.
