Our new GroVia line of AIOs are just....well...."like buttah" (channeling Mike Meyers on SNL). The inside construction and absorbency is exactly the same as our standard line, but the outer waterproof layer of TPU has been replaced with our proprietary laminated polyester velour. Shimmery, pillowy, and quite possibly the softest thing you've ever touched. The O.N.E diaper is the best all in one diaper (fits 10-35+ pounds) because it comes with everything parents need to cloth diaper a baby: enough absorbency to forget boosters and doublers (even overnight), two built-in closure options, and a heavy-duty construction that is built to last. The O.N.E. features a unique Outlast closure system that gives the user the ability to choose between Hook & Loop and Snap closures, and the ability to buy a replacement kit when your Hook & Loop wears out. O.N.E's absorbency comes from a hidden body layer PLUS our one-of-a-kind cotton, channeled soaker design that is trim yet absorbent.
