All diapers have the option for snap or velcro closure. The picture below is of the OS pocket diaper. NB diapers come as an AIO style.
These diapers are complete as is, there is no need for a cover. There is a full Layer of PUL for the new wick free style. PUL is under the print. There is even a strip of PUL to cover the seam where the fabric is sewn down to the PUL so that leaking won't happen through that seam. Make sure you lay your insert on top of this strip of PUL so that it isn't directly over the seam where the print is sewn to the PUL. Each diaper comes with one microfiber insert and OS diapers also come with a doubler.
Please remember that all sizes are approximate.
