- Two layers of PUL throughout (wipe-able interior)

- Double leg gussets

- Waist elastic at back and tummy 

- Two rows of waist snaps

- Interior PUL flaps to help keep diaper inserts tucked inside

- Insert snaps to snap Buttons inserts in place

- Compatible with all Buttons diaper inserts, but are best suited with Large and XL Buttons inserts.
