Nappy Covers

Covers to prevent leakage. This is the bit that keeps your babys clothes from getting wet. Covers can be made from PUL (polyurethane laminate), Wool or Polar fleece. Each type of cover functions in different ways and have their own advantages and disadvantages. You may also see other fabric types described as an outer such as minkee or cuddlefleece. These fabrics on their own are not waterproof, look for hidden layers of PUL or whether the fabric has been laminated to make it water resistant. PUL - short for Polyurethane Laminate which is applied to fabric to make it water resistant. Originally used in the medical field PUL is able to provide water resistant protection, withstand high heats and multiple washings, making it ideal for cloth nappies. PUL can be applied to many types of fabrics, the common ones in cloth nappy use are cotton and polyester and unlike plastic pants they offer a small degree of breathability. Often the terms waterproof and water resistant are interchanged (us included!). Any fabric that claims to be breathable will only be water resistant. This means for adequate protection you need to have enough absorbency in the nappy and frequent nappy changes otherwise leaks may occur. Cotton PUL is more likely to have leaks than a polyester PUL as it is an absorbent fabric and moisture may seep through the PUL to the cotton. If you are using cotton print PUL we suggest they are for day use only. PUL offers the trimmest nappy cover option. Wool – The natural qualities and properties of wool have a number of advantages over other fibres when used as a cloth nappy cover. Wool is naturally water resistant whilst it is able to store water vapour up to 30% of its own weight, yet it remains dry to touch and the thermal properties create a natural cooling system allowing skin to breathe, yet never feels damp and clammy. Wool is a durable fabric with the ability to stretch and recover, making covers that fit well while allowing body movement and they will last for years. Wool covers only need to be washed every couple of weeks and aired between wears. Wool should be hand-washed in luke-warm water using a suitable wool wash. They will also need to be lanolised every 4-6 weeks to retain their water resistance. Read our Washing Cloth Nappies section for more detailed instructions for caring for wool.
