The material used is not the typical PUL that you find with most other covers. This is made of a waterproof woven nylon material. It is a little bit thinner than PUL but its not a hugely noticeable difference.
One thing I was confused about on this diaper were the laundry tabs. One of the tabs has a flap on it to stick to it. The other side though does not. So when I put this in the washer I attached the one side to the tab and then hooked the two tabs together. They held during the wash.
Now this is the most unique feature I have seen on a cover. It has a vented opening in the back of the diaper. How neat! But to be honest I was worried it would look like a skirt on my little boy. As you can see it does flip up. Inside is a nice mesh like material to allow air to flow through it. On Pure Natural Essentials Navine put that she likes to flip this open when her daughter has a fever to help her cool down extra.
And Now the fit: I like the bright covers on this cover so I got a little extra photo happy...sorry!
On my 11 month old, with a prefold and snappi underneath this cover fit pretty well. I probably had it a little tighter than it needed to be but it didn't leave any marks.
Here is the back of the diaper. You can barely see the flap on the cover, so nope it doesn't look like a skirt!
A problem that I did have with this cover is that right at the top of each thigh I had trouble keeping the prefold in the cover. I had to tuck it up a lot to get it in but it kept coming back out. I also tried to readjust the velcro and placement of the cover to fix this problem but didn't have a lot of luck.
This isn't a bad little cover. The prints are so much fun. The velcro seems to be really good and looks like it will hold up well. Other than the fit of the cover on his thigh I really liked it. The vented back is a really cool feature to have. I wonder if I had a bigger size cover for him if the thigh/prefold exposure wouldn't be a problem.
