Everything You Need to Know About Bamboo Prefolds
Frequently Asked Questions
GroVia Bamboo Prefolds are reusable cloth diaper inserts made from a soft and absorbent 70% bamboo and 30% cotton blend. They feature a traditional 4x8x4 prefold construction, with extra layers of absorbency sewn into the center panel where your baby needs it most.
Yes. Bamboo prefolds are absorbent but not waterproof, so they must be paired with a waterproof cloth diaper cover to prevent leaks. They can be tri-folded (pad folded) and placed inside a cover or secured around your baby (360º absorbency) with a Snappi fastener before adding a cover.
Bamboo fibers are known for being highly absorbent and exceptionally soft, making bamboo prefolds a great choice for parents looking for a trim, comfortable, natural fiber diapering option.
Bamboo prefolds should be washed and dried 3–4 times before first use with warm water and an approved detergent. This removes natural oils from the fibers and helps them reach their initial absorbency. They will continue to become softer and more absorbent with additional washes.
Around 10% of natural shrinkage is expected and is part of the prepping process of the material which creates the absorbency for the product. Because bamboo fibers are more delicate than traditional 100% cotton prefolds, avoid hot water and high dryer heat, as excessive heat can cause additional shrinkage. Always wash in cool or warm water and tumble dry on low heat or hang dry.
For best performance, wash your bamboo prefolds every 2 days using a two-wash routine. This helps prevent odors, staining, and buildup while keeping your diapers fresh and absorbent.
Use a cloth diaper-safe detergent that provides proper cleaning without leaving behind residues. Avoid fabric softeners, as they can coat the fibers and reduce absorbency.
Yes. Bamboo prefolds are a popular choice for newborns because they are soft, gentle against delicate skin, and can be folded in multiple ways to create a customized fit. Be sure to choose the appropriate size for your baby.
GroVia Bamboo Prefolds are available in multiple sizes to fit babies as they grow. Each size is finished with a color-coded serged edge, making it easy to identify different sizes in your diaper stash.
Yes. Many families use bamboo prefolds for naps and overnight diapering because of their high absorbency. Depending on your baby’s age and wetting habits, you may choose to add additional absorbency for longer stretches.
