Our Sleep Onesie is a TOG-rated alternative to a sleeping bag, perfect for babies from 6 months through to preschoolers who prefer more freedom to move. Ideal for little ones who resist a sleeping bag, are toilet training, or moving from cot to bed, this relaxed-fitting design keeps children snug without blankets. Made from breathable, organic jersey cotton, the sleep onesie is soft on sensitive skin and gentle on eczema. Foot cuffs keep feet warm overnight, while a zip enclosure protects delicate skin.
