"I discovered I can't do without these. No matter what gets stuffed in them, they leave the skin dry. They dry so easily as well. A great addition to both Econoubum and Flip systems for a rash free, dry diaper. I agree that large prefolds won't easily fit, but with one fold down, it fits. Very quick to use. It fits every insert I use. Great addition to any diaper stash." ~ LeeAnne

This is not at all the product I thought it was based on the description. I don't even understand what the point of these things are. Seriously, what do you use them for? Whatever they are, they're not what I wanted, so now I've wasted my time and money and can't even return them because of course my husband opened them and threw away all the packaging. Maybe I'll turn them into sock pockets because they're useless to me otherwise.


These have been a saving grace for us!!! I had Bumgenius one size pocket diapers for my first daughter. My second daughter was extremely sensitive to them, and got a rash everytime she wore them no matter what we did. So we switched to prefolds with econobum covers, but then she would get an ammonia burn everytime.. So, we found these and they have switched us from switching to nasty, money wasting sposies! I love them, they wash up so nice and clean, she can wear it all night for bed, and wake up with a dry, rash free bottom! Definitely recommend these to EVERYONE!


Great product for sensitive skin. I wrap my flip organics in these and it's very dry against the skin. Good to use and wash separately if you need to use rash creams.


I wish these came in a value pack. When I purchased these I thought I was getting 3 socks. It is an excellent product but not very economical for my budget.


Great product. My son has sensitive skin, but these liners keep him from getting a rash. He can pretty much wear anything as long as this liner is laid on top. I only wish like one other reviewer said, the we could buy these in a value pack.
