The perfect insert if your superhero requires more absorbency for either nighttime or daytime. Designed to be used in any Super Undies item, these inserts add a varying amount of additional protection and absorbency.
Sometimes you just need to step up the absorbency, and that's where the flat comes into play! This versatile wash-cloth style insert is made from 100% (super thirsty) microfiber absorbency. Fold it anyway you need for maximum, customizable protection :)
