Wraps

All shaped nappies need a covering to keep baby's clothes dry.
There are several different varieties of wraps available, all with different qualities.

PUL (waterproof) wraps work by keeping wetness inside and away from clothing - Motherease airflow all for the most air circulation within the nappy/wrap.

Fleece works by allowing the moisture to pass through and evaporate - plenty of circulation, it can make clothes damp if the nappy is left to get sodden, or there is too much pressure (ie car set buckle) on the clothes & wrap for too long.

Wool is similar to fleece, but it also absorbs some of the moisture so it lets it evaporate more slowly leaving less chance for dampness on the clothes. It is a completely natural fibre so allows the most breathability for the nappy.
