ABSTRACT:
A sleeping bag having multiple sleeping compartments and including a first layer, a second layer, and a third layer. A first zipper is used to removably join the first layer to the second layer, defining a first sleeping compartment. A second zipper is used to removably join the second layer to the third layer, defining a second sleeping compartment. Each of the layers provides differing insulation characteristics such that each of the sleeping compartments have different comfort characteristics. The sleeping bag may be flipped over to provide different comfort characteristics in each of the first and second sleeping compartments. An indicator for indicating the comfort characteristic of each particular sleeping compartment is attached to at least one layer, providing a simple method of determining which sleeping compartment is the preferred choice for a given environmental condition. Alternative types and configurations of indicators are also disclosed.
