Waterproof seat covers for 2.5 gen front seats?

Hi all,
I am trying to find some actual/truly waterproof seat covers for my 2019 double cab tundra. For the back seat I have gone with a high quality dog cover that fits fine and is waterproof. For the front seats I'd like something cut to fit the actual tundra seats. I am an avid whitewater kayaker so I often have people in the truck that are wearing wet gear as we set shuttle, etc. so being waterproof is important to protect the fabric seats. I tried ordering these on Amazon but found them to fit very poorly so I returned them and not sure they were even waterproof (pretty sure they weren't!):

Anyone else have any recommendations with a link you could provide for a seat cover that actually fits the front seats of the 2.5 gen tundra and is actually waterproof?

 

I don't have a seat cover, but a lot of folks have spoken highly of Marathon. If you search around the forum you should find some folks who have them. They say they are weatherproof and I believe that was definitely in their Pros category from reviews I've seen.

I use these. They do a pretty good job.
