The O.N.E diaper is a true all-in-one diaper (fits 10-35+ pounds) that comes with everything you’ll ever 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. All with the same amazing quality you've come to know and love in GroVia products.
Let's talk about ONE by GroVia and it's No Prep qualities!
Okay, so. O.N.E. is built with SO much absorbency in its 100% preshrunk cotton soaker set that we are able to accurately describe it as a natural-fiber system with "no prepping required." Wash and dry it once for safety and cleanliness, as you would with any garment, before placing on your baby, and it's EASILY good to go for your normal 2-3 hours of daytime diapering, even for a moderately heavy wetter! Game-changer, indeed!
However! Game-changer though this design is, cotton is still cotton, and cotton fibers are ALWAYS going to gain absorbency after several washes and tumble-drying sessions. So if you're purchasing O.N.E. right now specifically for nighttime diapering or if you know your child is an *exceptionally* heavy-wetter, prep it. Wash it on Warm or Hot with plenty of good-cleaning detergent and tumble dry in between, three times, before attempting to get 12+ hours leak-free out of your O.N.E. Diaper.
Alternatively, you could use it during the daytime until it's been through the washer and dryer 3-4 times and has become "night-worthy"... just be warned that you may fall in love with O.N.E. as a daytime diaper.
