Cotton Babies One-Size Microfiber inserts are made of 3 layers of the thickest microfiber terry available anywhere. Our unique snap down design allows these inserts fit perfectly in a small, medium or large Happy Heiny's or at any rise setting on a bumGenius! Our new, wider and longer design fills up Wonderoos and Happy Heiny's side-to-side and end-to-end. No more leaks!
Our one-size inserts dry as quickly as Wonderoos or Happy Heiny'sdry on the line or in a dryer. All the economics of a one-size product and no more waiting for thick cotton or hemp inserts!!
Our inserts are now manufacturer rated at 15 oz. aborbency. No other microfiber insert compares. We recommend using two inserts when diapering an older baby or toddler at night.
You only need a tiny bit of detergent to get these inserts clean.
Less detergent, less energy (our inserts are easy to hand wash/line dry if necessary), convenient one size design, and a lower price make these inserts the absolute best value available anywhere.
