No magic tricks! Just a smart solution that will make this kids’ sleeping bag last for many many seasons. The Husky KIDS MAGIC -12 °C can be shortened or extended by attaching or detaching the bottom part. The shorter version - suitable for kids up to 125cm tall - the detached part can be used as an insulated sack for keeping your feet warm. The longer bag can be used when your child is up to 155cm tall. That means that the Kids Magic -12 °C is ideal for kids from a young age up to adolescence - for hikes in the nature, canoeing trips or trekking.
