Best Bottoms recommends having 3 inserts on hand for each shell. When you change the insert, you will not always need a new shell because they are wipe-able and reusable! To Order Extra Best Bottom Shells Click Here!
Best Bottom offers two different types of regular inserts that snap into the Best Bottom Snap or Hook & Loop Shells. Choose between a Stay Dry Insert or a Hemp/Organic Cotton Insert. Each comes in 3 different sizes. This size chart will help you choose the correct size, but remember sizing depends on the size and shape of the baby as well as how heavy of a wetter the baby is:
Small: Birth-14 pounds
Medium: 11-22 pounds
Large: 16-35+ pounds
The Stay Dry Insert is made of 4 layers of super thirsty microfiber topped with a soft no-pill fleece that will pull wetness from your baby's bottom to keep your baby feeling dry.
The Hemp/Organic Cotton Insert has 5 layers of Hemp/Certified Organic Cotton and is topped with a soft layer of Hemp/Certified Organic Cotton Fleece. This is a very absorbent but trim insert!
The Micro Overnight Insert is made of 6 layers of super thirsty microfiber! You can also choose the Hemp/Organic Cotton Overnight Insert. The Overnight Insert is made to fit under any same size regular insert - Micro or Hemp/Organic Cotton. Just snap the Overnight Insert into the Best Bottom Shell and then snap a regular insert on top - no more nighttime leaks! The Overnight Insert is under the regular insert so only the Stay Dry microfiber or the Hemp/Organic Cotton will touch your baby.
As an added option, Micro Doublers are available. The 2 layers of thirsty microfiber makes the Micro Doublers great for long naps, long car rides and heavy wetters! The Micro Doubler is made to fit with any regular insert of the same size. Just snap it into the cover and then snap a regular insert on top.
