Twoosters (TM) are a booster made of two fabrics - hence the name. Two layers of absorbent terry topped with a third layer of polyester fleece, and cut to the familiar Twinkle hourglass shape. Specially designed to minimise the number of separate layers you need, the fleece layer of the Twooster will keep your baby dry and at the same time the two layers of terry will provide extra absorbency. Simply pop one of these on top of your nappy fleece side up instead of using a booster and a separate liner. Great for childcare use too. White, wash any temperature, can tumble dry.
