Your kids grow with every adventure they go on – and so does the GROW UP KIDS. Designed for the smallest outdoor fans (and slightly larger ones), this children’s sleeping bag has a variable length.Hidden in the foot section is a zip that allows you to extend the bag. This sleeping bag is perfect for holidays, school trips and camping adventures. It features our MICROGUARD synthetic fibre insulation. The big advantage of MICROGUARD is that it is insensitive to moisture, so it retains its insulation performance even when damp. A double layer of insulation in the foot box keeps sensitive little feet warm and cosy.
