Also introducing a new color for Knickernappies: Chocolate! A fabulous new color perfect for boys or girls. Which insert should I choose?
 Microfiber inserts are absorbant and economical. Use one for daytime or two for nights and naps. 3 layers of microfiber.
LoopyDo inserts are the #1 insert on Diaper Pin. Combining both hemp and microfiber makes them both absorbant and trim. Sewn in a loop so they dry fast, prewashed so they're ready for use after just one wash.
What makes Knickernappies OneSize diapers the best choice? - Side snaps make the diaper smooth and non-bulky in the tummy area.
- Easier to pull pants over side-snapping diapers.
- Harder for babies to undo by themselves.
- For potty training, they can be pulled up and down like underwear without undoing the snaps.
- Snaps are long-lasting and easy to care for.
