BumGenius One-Size Microfiber inserts are made of 3 layers of the thickest microfiber terry available anywhere. This unique 2 snap down design allows these inserts fit perfectly in a small, medium or large.

Drying time:
Our one-size inserts dry as quickly 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!!

Absorbency:
Our inserts are now manufacturer rated at 15 oz. aborbency. Many other companies offer microfiber inserts now, but no other microfiber insert compares to the bumGenius microfiber insert. What is different? Our product is simply more absorbent than the others.
