Best waterproof blankets for pee play?

[twentyq 1]

What's the best waterproof blanket out there for pee play without making a mess? 

It seems like the No More Wet Spot would be a good option, but it's not clear if it's meant to actually contain a bladder or two worth of liquid. 

Does anyone have experience with a blanket that works well?

Hi, I don't know where you are but I'm in the UK and I use one of these mattress protectors, comfortable and fully waterproof, can be washed and tumble dried on a low heat. I did try the pillow ones as well but they weren't as effective.
