Abstract
This invention reduces the weight and bulk of the hiker's backpack by eliminating the sleeping bag as a separate item. This is accomplished by providing insulating walls in the knapsack and providing the knapsack with a foldable insulating extension so that the insulated elongated knapsack can be attached to the bottom end of a parka to provide a continuous enveloping sleeping bag.
