A 6-ply doubler for any diaper or use an insert to layer into a pocket diaper to replace microfiber inserts. Made from Cloth-eez Prefold fabric. Measure the size of what you want to replace to be sure of your correct size. Because these are 100% cotton, they can be used next to baby's skin. Doublers, (boosters) and these cotton Inserts are all similar but are different sizes and layering. A 6-ply doubler-insert to layer into a pocket diaper replace microfiber inserts. These are 6-ply. That means six layers of cotton prefold fabric, which is 2 layers less than our other doublers, however they are wider. One is NOT enough in a pocket diaper, except for a very young baby. Layer 2 or even 3 of these in the pocket to get the absorbency you want. We chose to make these 6-ply because they dry very fast, wash cleanly very easily, and allow for customized absorbency needs. Want it trim? Use 2. That is 12 layers. This is the most common way to use these. Need more absorbency? Use 3 of them in there. Choose your bulk-level; choose your correct absorbency for your needs. The big benefit of these is how easily they come clean in the wash. Say goodbye to stinky microfiber. Use them for dusting instead. The skin on your hands will be happier too when you stop touching the microfiber inserts. Cotton feels so much nicer. Should you decide to move away from synthetic pocket diapering and switch over to 100% cotton diapering, you don't need to purchase any doublers because you already have these on hand. The same lovely prefold fabric as our beloved Cloth-eez® prefolds. These are wider than our regular Cloth-eez doubler for a better fit when stuffing synthetic pocket diapers. They are quilty just like prefolds are so they come out of the dryer curly and need to be flattened out by hand a bit. This is the nature of the twill prefold fabric. These are also suitable as doublers for extra absorbency in any style diaper. Measurements are approximate. Shrinkage varies. Chlorine-free white 100% cotton. Made in Pakistan. Stacking 3 large blue edge inserts is similar to using one medium red edge prefold diaper. So if a medium prefold is too much bulk for your pocket diaper, try using just 2 of these doubler-inserts for a trimmer fit. Stack them together, grab both ends together and place it into the pocket all at once, as if it were one item, at the same time. Stuffing two is not very different than stuffing one because it is still one stuffing motion. 12 layers would be too thick to wash and dry so using two 6 layer inserts together in the pocket really does makes sense. Need more for nap or night? Use 3 at the same time. What is the difference between a doubler and and insert? The width and the layering are a little different but they very similar. You can use these as doublers. Inserts are a little bit wider than doublers and the width is needed to fill up the space in the pocket. These are 6 ply. There are many choices for absorbency but something that is 100% cotton will always wash up more easily than any other absorbency fabric. See a video explaining the inserts and comparison to prefolds Prefold fabric is quilty, curly and variable. Sizes are approximate. Shrinkage will vary. They come out curlier and a little smaller when prepped and washed in a front loader or an HE top loader due to the action of the HE machines (pushing fibers vs pulling fibers). They tend to come out a little flatter when prepped and washed in standard top loader. This machine and shrinkage variation is also true for prefolds, flats and other cotton products. What do you insert these Inserts into? Any pocket diaper. Choose your insert size according to the length of the pocket diaper at the rise setting you are using for your child. Medium Prefold with a medium Insert used as a doubler shown on a changing table with a curved changing pad on it. Medium Inserts are shorter than medium Prefolds. Medium Inserts are closer in length to a small Prefold. Small or Novice Prefold are another option. See the video. All Cloth-eez cottons are Oeko-Tex certified standard 100. Tested for safety.
