I have been using weehuggers/ thirsties/ Flip wraps with Flip organic inserts for a while now.
A few weeks ago i had run out of clean inserts so used an issy bear night insert (just single one) inside a flip cover, it fitted the shape of the nappy (on middle setting) brilliantly, fitting right up to the edges, was a lot trimmer than flip organic, lasted 4hours and contained a very runny poop without any going on the wrap
I have since bought 8 more of the inserts (only £3 each from C&C not on website but are available if you email). I have used them in thirsties duo wrap and weehuggers and they fit really well and last about an hour longer than a flip organic.
At only £3 each they are incredibly absorbant and much cheaper than flip or weehuggers inserts, just thought i'd share for all of you that use 2 part systems
