Mix and match our TOG-rated Layers, designed to be worn as a pyjama underneath any of our swaddles, sleeping bags, sleep suits or sleep onesies. They're so sweet, we guarantee you'll want extra for daywear too! Our Layers are made from a deliciously soft, stretchy organic jersey cotton for comfort and warmth during sleep. The slim-fit design prevents bunching underneath your child's pouch, and the breathable, natural fibres help regulate body temperature and prevent overheating. Parents can follow the FREE room thermometer and What to Wear guide provided with our pouches to find the perfect under-layer for their little one, whatever your room temperature*. The 1.0 TOG Layer is a thick long sleeve bodysuit for newborns, babies and toddlers, ideal for cooler nights when you need extra warmth under the pouch.
