Best Bottom has created two different types of Regular inserts (hemp and stay-dry) to snap into their shells for everyday use.

You can mix and match meeting all preferences and needs. Both insert types are super trim making the Best Bottom one size diapering system one of the trimmest cloth diapers around. 

Sizing is approximate and will depend on size and shape of baby as well as how heavy of a wetter.

Small: birth-14lbs, Medium: 11-22lbs, Large: 16-35lbs.

The Hemp/Organic Cotton Insert consists of 5 layers of hemp/Certified Organic cotton topped with a soft layer of hemp/Certified Organic cotton fleece. This insert is so trim you will be able to have your baby wear jeans again! Please note that hemp inserts will shrink slightly during first washings making them consistent with the other insert sizing.
