The Smart One 3.1 cloth diaper from Smart Bottoms is a one-size, all-in-one diaper that is available in bold solid colors with accent colored snaps as well as fun prints. The trim design will fit under most clothing, so there's no need to buy the next size up in clothing just to fit over the diaper. This is one of the most absorbent one-size diapers on the market and can be used on most children from birth until potty. (Approx. 10 -35 pounds)

All-in-one diapers have the waterproof cover on the outside (heat-adhered PUL) and the absorbent diaper (organic cotton) material sewn to the inside. The Smart One 3.1 has an adjustable tongue style insert that allows you to customize the absorbency, too! These diapers are used, washed and then used again! There are no confusing parts to be sorted - just use it right out of the dryer as is.

Only the Best for Your Baby
Smart Bottoms uses only 100% certified organic cotton inside their diapers. Your baby’s skin will not be exposed to harmful pesticide residue or petroleum based fabrics when you use Smart Bottoms. The natural fibers will reduce, if not eliminate, diaper rashes as well as promote early potty learning.

Prepping Your Diapers
Because Smart Bottoms uses 100% Certified Organic Cotton Fabric, it will take 6-8 washes before your diapers are fully absorbent. No chemicals are used to strip the natural oils from the fabric, so it will take a few extra washes before they are ready to use, but it will be so worth it! How hard your water is, the type of detergent you use, and what type of washing machine you have will all factor in to exactly how many washes it takes to fully prep your diapers. We recommend testing a dry diaper before you use it the first time by pouring a small amount of warm water on your diaper. If it absorbs instantly, your diapers are ready to use! If it takes even a few seconds to absorb, wash a couple more times and try again.
