This is the waterproof Echo Shell only with snap closures, so be sure to include Pods or Mini Pods before you check out. The SoftBums Echo System lets you build a custom diaper for your baby! SoftBums Diapers are a unique system made right here in Minnesota. It's a one-size-fits all cover with replaceable inserts. Fits all legs widths from 4" - 14" for NO red marks. Similar to a pocket diaper, the inserts have a layer of light-weight fleece so that moisture wicks away from baby's skin and is absorbed by super-absorbant microfiber. Unlike a pocket diaper, the cover can be used several times between washes, usually three times. That means that each basic set is equivalent to buying 3 pocket diapers. The cover expands via adjustable elastic to fit 6 to 35 lbs, fitting newborns to toddlers. We've gotten a LOT of great feedback from customers about these. Made in Minnesota.
