ABSTRACT:
A three-dimensional vacuum envelope is provided for storing compressible articles and particularly survival equipment such as a parachute. It includes upper and lower walls of flexible, substantially gas-impermeable material. One of the upper and lower walls includes an integral loop defining a pouch in fluid communication with the remainder of the envelope. The pouch is pivotable with respect to the envelope and may be used for containing parts which must be independently maneuverable even after storage and evacuation.
