Product Details

When it comes to cloth diapering, versatility and comfort are everything. Our new Kinder™ Bamboo Viscose Cotton Lycra PreFlat is thoughtfully designed to make diaper changes simple, snug, and sustainable.

What Is a PreFlat?
A PreFlat is a modern update to the traditional flat diaper. Instead of a plain square of fabric that requires folding, the PreFlat features built‑in wings and a contoured shape that wraps easily and securely around your baby. It combines the custom fit of a flat with the ease of a fitted, giving you the best of both worlds.

Standard OS Fit - Fits most from 10-35 pounds. 

Listing is for one pre-flat diaper, outer water resistant cover is sold separately. 

Why Parents Love PreFlats

  • Adjustable Fit: Fold and secure your PreFlat in multiple ways to suit your baby’s shape and size.
  • All‑over Absorbency: Soft, absorbent layers capture wetness from every angle for reliable leak protection.
  • Gentle Breathability: Made with natural fibers that stay cool and comfortable against sensitive skin.
  • Quick Drying: Washes easily and dries faster than bulkier fitted diapers.
  • Budget‑Smart Flexibility: Pair with boosters, covers, or different folds as your baby grows. One diaper, endless options.

Bamboo Cotton Comfort—with a Little Stretch
Crafted from a super‑soft blend of 68% bamboo viscose, 28% cotton, and 4% spandex, our PreFlat offers the ideal balance of softness, stretch, and strength.

  • Bamboo viscose brings silky comfort and natural temperature regulation.
  • Cotton adds durability and breathability.
  • Spandex (lycra) provides a gentle stretch for that perfect, secure fit around legs and waist.

The result? A cloth diaper that’s absorbent, flexible, and luxuriously soft for everyday comfort.

PreFlat+ Booster Edition
For families needing extra absorbency—especially for naps or overnight—the PreFlat+ Booster Edition includes an ultra‑thirsty Zorb core made from bamboo viscose and organic cotton. This added layer boosts capacity without bulk, offering peace of mind for heavy wetters or extended wear.

Customer video review of Bamboo Viscose and Cotton Lycra Stretchy Pre-Flat Diaper

I have an 11 pound 10 week old and a 25 pound two year old. It definitely takes a little trial and error but once you learn how to fold them to fit your baby these are amazing! (In the video I’m showing how I fold these for my newborn) I personally am not a fan of pocket diapers, but these are so great. They have full coverage that contains everything. Pair it with a solid cover and I have had little to no blowouts. I pair these with a stay dry liner to help with staining and for comfort. I got the overnight boosted preflats for all day use and they are great, I do have to add a small booster to my toddlers diaper and it’s a little bulky but these have helped my toddler with potty training because she can feel when she’s wet and has started recognizing that she needs to use the potty. These are super soft and holding up great, very minor pilling/fraying while washing every other day.

Customer video review of Bamboo Viscose and Cotton Lycra Stretchy Pre-Flat Diaper

First attempt at preflats went super smoothly. These are very soft and thick however trim at the same time. Purchased for underneath wool covers and they work great. I got just 5 to start but will be ordering more.

Customer video review of Pre-Flat+ Nighttime Diaper Value Bundle

I love these pre-flats so much! They are so great for nighttime diapers. They last my baby for at least 11 hours with no leaks! I was hoping to find something to make our nighttime diapers, a lot easier, and less bulky. And these are an amazing solution, and the best option. I’ve tried so far. They also dry really easily after washing and fit great in the new hybrid covers! I’ve been a pocket diaper and insert girlie for three years now, but I think I may start switching up to more preflats and covers :)

Customer video review of Bamboo Viscose and Cotton Lycra Stretchy Pre-Flat Diaper

I am obsessed to say the very least! I love these preflats more than I thought I would! I typically use prefolds and love them. When I ordered these preflats I wouldn’t have guessed I would end up preferring them to prefolds! They have so much stretch to them which I love because that is the one thing I don’t like about the prefolds I use. I am sure these are the ones my boy prefers too as they are so soft. If you like prefolds you will love these.

Bamboo Viscose and Cotton Lycra Stretchy Pre-Flat Diaper

Love these stretchy prefats! I use pins and find them easy to use. It is so much easier than a cotton prefold diaper. No troubles with leaks or absorbing even with a toddler. They did fade in the wash already, which I’m sad about because I love the colors. But I’m not surprised they faded since I use hot water and wash diapers twice each wash day. They’re a fun addition to my stash and will stay in the regular rotation.

Bamboo Viscose and Cotton Lycra Stretchy Pre-Flat Diaper

We've used Esembly since birth, but noticed the Size 2 diapers were falling apart and having constant leak issues so decided to try these preflats to replace them. We absolutely love them! Easy to use, and we went from needing multiple boosters for overnight, still getting leaks, to just one Preflat+ with no leaks. Only minor downside is that they take longer to dry, but it's worth the trade off.

Bamboo Viscose and Cotton Lycra Stretchy Pre-Flat Diaper

These preflats are AMAZING. So soft, so easy to use, and they hold up incredibly well. I love how customizable the fit is, and they’re not bulky at all. They’ve made cloth diapering even easier for us. I’ll definitely be ordering more — obsessed!

After 1 wash with tide it looks bleached. (We never use bleach in any load)

Store owner replied: Thanks for taking the time to share your feedback. Someone from our care team will be reaching out soon to grab a few photos so we can share them with our research and development team. We always appreciate the chance to learn and make things better.

Any plans for a newborn smaller size if these go off well? I can make this fit on my 11 lbs baby but it definitely was fiddly and a bit bulky. On the other hand love the soft material.
