## 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.

## Claims

### Claim 1

A multiple layered sleeping bag having a first side and a second side comprising;
a first layer;
a second layer;
a third layer;
a first zipper removably joining said first layer and said second layer and defining a first sleeping compartment having a first insulating characteristic;
a second zipper removably joining said second layer and said third layer and defining a second sleeping compartment having a second insulating characteristic different than the first insulating characteristics; and
a first indicator located in proximity to the first sleeping compartment, the first indicator providing an indication of the first insulating characteristics and the suitability of the first sleeping compartment climatic conditions; and
a second indicator located in proximity to the second sleeping compartment, the second indicator providing an indication of the second insulating characteristics and the suitability of the second sleeping compartment for second climatic conditions different than the first climatic conditions.

### Claim 2 (depends on 1)

The sleeping bag as recited in claim 1 wherein:
said first indicator comprises a first label indicating an estimated temperature range for said first sleeping compartment; and
said second indicator comprises a second label indicating an estimated temperature range for said second sleeping compartment.

### Claim 3 (depends on 2)

The sleeping bag as recited in claim 2 wherein:
said first label is attached to one of said first layer and second layer; and
said second label is attached to one of said second layer and third layer.

### Claim 4 (depends on 1)

The sleeping bag as recited in claim 1 wherein:
said first indicator comprises a tag attached to said first zipper; and
said second indicator comprises a tag attached to said second zipper.

### Claim 5 (depends on 1)

The sleeping bag as recited in claim 1 wherein said first indicator comprises a temperature measuring device.

### Claim 6 (depends on 1)

The sleeping bag as recited in claim 1 wherein said first layer has a first thermal insulation property, said second layer has a second thermal insulation property and said third layer has a third thermal insulation property.

### Claim 7 (depends on 1)

The sleeping bag as recited in claim 1 wherein said first thermal characteristic is substantially equivalent to said second thermal characteristic.

### Claim 8 (depends on 1)

The sleeping bag as recited in claim 1 and further comprising:
a fourth layer; and
a third zipper removably joining said third layer and said fourth layer to define a third sleeping compartment having a third comfort characteristic.

### Claim 9 (depends on 1)

The sleeping bag as recited in claim 1 wherein said first zipper is compatible and interconnectable with said second zipper.

### Claim 10

A multiple layered sleeping bag having a first side and a second side comprising:
a first layer;
a second layer coupled to said first layer along said first side of said bag;
a third layer coupled to said second layer along said second side of said bag;
a first zipper removably joining the first layer to the second layer along the second side of said bag, said first zipper defining a first sleeping compartment having first insulating characteristics;
a second zipper removably joining the second layer to the third layer along the first side of said bag, said second zipper defining a second sleeping compartment having second insulating characteristics different then the first insulating characteristics; and
an indicator attached to at least one of said layers for indicating at least one of said first and second insulating characteristics of the associated first and second sleeping compartments.

### Claim 11 (depends on 10)

The sleeping bag as recited in claim 10 wherein said indicator is attached to said first layer.

### Claim 12 (depends on 11)

The sleeping bag as recited in claim 11 wherein said indicator comprises a tag having indicia and being attached to said first zipper.

### Claim 13 (depends on 11)

The sleeping bag as recited in claim 11 and further comprising a second indicator attached to said first layer.

### Claim 14 (depends on 12)

The sleeping bag as recited in claim 12 wherein said second indicator comprises a tag attached to said second zipper.

### Claim 15 (depends on 10)

The sleeping bag as recited in claim 10 and further comprising:
a fourth layer coupled to said third layer along said first side of said bag; and
a third zipper removably joining the third layer to the fourth layer along the second side of said bag, said third zipper defining a third sleeping compartment.

### Claim 16 (depends on 10)

The sleeping bag as recited in claim 10 wherein said indicator is a label indicating a thermal insulation property for at least one of said sleeping compartments.

### Claim 17 (depends on 10)

The sleeping bag as recited in claim 10 wherein said indicator is a label indicating a padding characteristic for at least one of said sleeping compartments.

### Claim 18

A multiple compartment sleeping bag comprising:
a first sleeping compartment having a first layer, a second layer and a first zipper removably joining said first layer and said second layer, said first sleeping compartment having first insulating characteristic;
a second sleeping compartment having a third layer and a second zipper for removably joining said third layer and said second layer, said second sleeping compartment having second insulating characteristics different than the first sleeping characteristics; and
an indicator attached to said first layer adjacent to said first zipper for indicating said first insulating characteristics.

### Claim 19 (depends on 18)

The sleeping bag as recited in claim 18 and further comprising a second indicator attached to said first layer adjacent to said second zipper for indicating said second comfort characteristic.

### Claim 20 (depends on 18)

The sleeping bag as recited in claim 18 wherein said indicator is a label.
