Alta Junior Flex sleeping bags adjust in length for children between 130-160 cm tall. Simply push the foot-end into the bag and zip it up for a shorter length and extra insulation for younger kids. Based on our popular Alta sleeping bag, Alta Junior Flex is suitable for spring, summer, and autumn use, while Alta Winter Jr. Flex provides warmth for winter camping. With red markings for easy handling, the Junior Flex series is designed with two layers of lightweight fiber to minimize heat loss.
