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. Our Layers are made from a deliciously soft, stretchy organic jersey cotton for comfort and warmth during sleep. The slim-fit designs 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 layer, ideal for cooler nights when you need extra warmth under the pouch. Full of handy features such as 3-way zips for easy nappy changes and dressing, foldover hand and foot cuffs, and zip guards. Our GOTS certified organic fibres are skin-friendly and sensitive on eczema and dry skin conditions. All ergoPouch fabrics are dyed with non-toxic water based dyes, and come in trend-driven prints and colours to suit any nursery. All our prints are designed in-house. *Note, the thermometer is not included with this product.
