This Done by Deer wearable sleeping bag prevents children from kicking off covers and delivers comforting warmth with a TOG 2.5 rating for colder nights. This baby sleep sack features adjustable armholes with snap buttons to refine the fit as the child grows, plus a YKK safety zipper for smooth dressing and fast diaper changes. This nursery sleep bag pairs a 100% cotton outer fabric with polyester fibre filling for breathable softness and consistent insulation. This wearable blanket arrives in a soft sand colour with Dotti, Pigee and Sheepy motifs, offering a calm, modern look that complements neutral nurseries.
