Bumberry Wetfree Microfiber inserts has an additional 'wet-free' microfleece fabric as the skin facing outer layer helping the baby to remain dry during its usage. Bumberry Wetfree Microfiber insert has three more layers of highly aborbent microfiber which functions to help for faster absorption. Market proven and won already the trust of many mothers, the Bumberry Wetfree Microfiber offers longer diapering hours, but we recommend to limit the time of use of one insert to be lesser than 6 hours maximum as paediatricians world over recommends not to use any diaper for more than 6 hours. Bumberry Wetfree Microfiber insert performs excellently with a Bumbery Diaper Cover model. At the same time, it also could be used with a Bumberry Pocket style Diaper for higher absorption levels.
