It is not particularly breathable, you can't use it in the summer. It's so hot that you sweat!

I have it for a month, I got it for my little one's mattress that leaks, we had an accident but it didn't pass to the mattress. It does its job well

I had washed it and put it for over six months and it didn't suffer anything. It retains moisture and doesn't seep into the mattress. It was a bit difficult to dry during the winter months, but those who have a proper place to hang it won't have a problem.
