I am currently in this diaper this morning and going on four hours. It is holding up beautifully without any tape peel. The fit is just about perfect, a 47" waist size is the cut off for my frame, so I cannot go lower in size. The comfort level is great inside with softness and absorbency. The outside plastic feels soft and strong against the skin without a lot of crinkle which makes the diaper discreet. I like Lunar Cubs but they're a limited time run and for me there is no extra room compared with the other diapers in the Rearz lineup.

These are the best, most absorbent, most comfortable and my favorite plastic material. Ten stars. These are my new absolute favorite thing.
