Keeping baby cosy and safe when sleeping, this adorable Ollie Owl print 1 tog sleep bag from Tommee Tippee ensures even the wriggliest of little ones are kept snug, with no blankets to kick off. Designed to allow a natural hip and leg position for comfortable and healthy bedtimes, the tog measurement helps you to prepare baby for bed according to the temperature. Made from super-soft cotton for delicate skin, the zip opening makes for easy night-time nappy changes, unzipping from the bottom to keep them warm at the top with minimum disturbance. Good to know: A tog measurement is a European warmth rating: the higher the tog, the warmer the product. Tommee Tippee baby sleep bags are available in 0.2, 1.0, 2.5 and 3.5 togs. Always ensure you dress your baby in the correct clothing to suit your room temperature, see Tomme Tippee packs for guidance.
