The ergoPouch Long Sleeve Layers were designed to be worn as pyjamas underneath any swaddle, sleeping bag, sleep suit or sleep onesie. 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 ergoPouch room thermometer and What to Wear guide provided with ergoPouch swaddles and sleeping bags to find the perfect under-layer for their little one, whatever your room temperature! The 0.2 tog Layer is a mild layer. 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 prints are designed in-house. *Note, the thermometer is not included with this product. GOTS certified organic cotton Slim fit and stretchy Fold over cuffs for hands and feet 3 way zip
