Meet Invader One Size Diaper Covers - A colorful, digitized space invader themed cloth diaper print introduced in 2014. The Rumparooz One Size Cloth Diaper Cover is designed to grow with your baby, with 4 adjustable rise settings; newborn, small, medium and large. Weight range of cover starts at 6 pounds and will fit up to approximately 35+ pounds. Rumparooz One Size Cloth Diaper Covers are generously sized and designed to fit over most fitted or prefold diaper. Covers may be used multiple times before washing but should be placed into the laundry if it becomes soiled. Kanga Care uses a water resistant polyester TPU which is a solvent-free polyester fabric that has been laminated with a thermoplastic polyurethane using a heat bonding process, not chemicals. This process is low in toxicity and is better for the natural environment then traditional PUL.

The interior uses a water resistant polyester TPU that is laminated using a heat bonding process, not solvents. This construction is lower in toxicity and gentler on the environment than traditional laminated fabrics.

Designed to fit over most fitted diapers and prefolds, the cover gives you flexible, economical diapering options. Covers can often be used several times between changes if they are not soiled, saving loads of laundry.

Snap the rise to newborn, small, medium or large for a secure fit from about 6 to 35+ pounds. Elastic leg gussets and snap closures help stop leaks while keeping the fit comfortable as baby grows.
Pick a cover that fits your routine, your washer, and the types of absorbents you plan to use.
- Match Your Absorbents: If you plan to use prefolds or fitteds, choose a roomy cover with secure leg gussets and snaps.
- Think Long Term: One size covers with multiple rise settings reduce the need to buy several sizes as baby grows.
- Check Material Safety: Look for solvent-free, heat-bonded TPU or similar water resistant fabrics to minimize chemical exposure.
- Laundry Practicality: Covers can usually be used multiple times if not soiled, but plan for regular washing and quick drying options.
- Leak Protection: Prioritize elastic leg gussets and secure closures to keep leaks contained with active babies.
What size range does this cover fit?
The cover snaps down to four rise settings and is intended to fit from about 6 pounds up to approximately 35+ pounds.
Can I use this cover with prefolds or fitted diapers?
Yes, the Rumparooz One Size Cover is generously sized and designed to fit over most fitted or prefold diapers for flexible diapering.
Do I need to wash the cover before first use and how do I care for it?
Yes, wash once before first use. Recommended care is a cold rinse, hot wash with recommended detergent, cool rinse, then tumble low or lay flat to dry.
Is the TPU material safe for baby and the environment?
Kanga Care uses a solvent-free polyester TPU laminated with thermoplastic polyurethane by heat bonding, a lower toxicity process compared to some traditional laminates.
