Why Do You Need a Waterproof Cover for Bamboo Fitted Nappies?

When it comes to cloth nappying, bamboo fitted nappies are a fantastic choice for their superior absorbency, softness, and eco-friendliness. However, one crucial component that can often be overlooked is the need for a waterproof cover. Unlike traditional modern cloth nappies, bamboo fitteds don't have a sewn in waterproof layer. 

In this guide, we’ll explain why our bamboo fitted nappies need a waterproof cover and help you decide which waterproof cover is best for your needs. At Mimi & Co, we offer two excellent options: the wipeable TPU cover and the wool cover.

Why Do Bamboo Fitted Nappies Need a Waterproof Cover?

Bamboo fitted nappies are highly absorbent and can hold a significant amount of moisture. While this is great for keeping your baby dry, it also means that without a waterproof cover, the moisture can easily seep through to clothes and bedding. A waterproof cover acts as a barrier, preventing leaks and keeping your baby’s bottom dry and comfortable.

Benefits of Using a Waterproof Cover

  1. Leak Protection: The primary function of a waterproof cover is to contain moisture and prevent leaks. This is especially important during naps and overnight, when your baby may not be changed as frequently.
  2. Versatility: Waterproof covers can be used over various types of nappies (even disposable nappies), making them a versatile addition to your nappying routine.

Choosing the Right Waterproof Cover

At Mimi & Co, we offer two types of waterproof covers: the wipeable TPU cover and the wool cover. Each has its unique features and benefits.

1. Wipeable TPU Cover

  • One Size Fits Most: Our TPU cover is designed to fit most babies from birth to potty training. This means you only need to invest in one set of covers as your baby grows.
  • Easy to Clean: The wipeable TPU material makes cleaning a breeze. Simply wipe down the cover between uses, and it’s ready to go.
  • Lightweight and Breathable: TPU covers are lightweight and breathable, ensuring your baby stays comfortable even during warmer weather.
  • Durable and Reliable: TPU is a strong, durable material that can withstand frequent washing and use.

2. Wool Cover

  • Natural and Breathable: Wool is a natural fibre known for its breathability and temperature-regulating properties. It keeps your baby warm in winter and cool in summer.
  • Highly Absorbent: Wool can absorb up to 30% of its weight in moisture before feeling wet, making it an excellent choice for overnight use.
  • Odour Resistant: Wool naturally resists odours, reducing the need for frequent washing. You will only need to wash your wool cover every 4-8 weeks (or unless it gets too poo on it).
  • Available in Four Sizes: Our wool covers come in four sizes to ensure a perfect fit as your baby grows.
  • Lanolin Treatment: Wool covers require occasional lanolin treatment to maintain their waterproof properties after each wash. This natural treatment helps keep the wool soft and effective.

Which Waterproof Cover is Best for You?

The choice between a wipeable TPU cover and a wool cover depends on your specific needs and preferences.

  • For Everyday Use: If you’re looking for an easy-to-clean, versatile cover that fits most sizes, the wipeable TPU cover is a great option. Its simplicity and durability make it perfect for everyday use.
  • For Overnight and Sensitive Skin: If you need a cover that offers superior absorbency, breathability, and is gentle on sensitive skin, the wool cover is the way to go. Its natural properties and temperature regulation make it ideal for overnight use.


A waterproof cover is an essential component of your bamboo fitted nappy system, providing leak protection, comfort, and extended use. Whether you choose the wipeable TPU cover or the wool cover, you can rest assured that your baby will stay dry and comfortable throughout the day and night.
