An innovative design that makes a fantastic investment, our 3-in-1 Dinosaur Print Sleeping Bag offers comfort without compromise as you\'ll be able to change the snugness of it during any season. It comes with one under 1 tog sleeveless sleeping bag and one approximately 2.5 tog sleeveless sleeping bag. You can attach both bags at the base with an easy zip to make a cosy 3.5 tog bag for winter, or they can be worn separately to suit the temperature, whatever the time of year.
