When temperatures can jump from -1C to 21C, the Coleman 2-IN-1 Sleeping Bag is the ultimate sleeping solution. This sleeping bag has a unique convertible design that is perfect for varying weather conditions and temperatures. In warmer weather, the sleeping bag can be left in its hybrid form. The hybrid form has vents on the side and foot of the sleeping bag to provide ventilation and help you keep cool while you sleep. If the temperature drops, simply turn the bag into a mummy by zipping the vents to trap in all the warm air.
