Abstract: An integrated ensemble for personal protection and comfort. The integrated ensemble may generally include one or more multifunctional layers. Each layer may include functionality directed to provision of specific types of protection and/or personal comfort. A liner may be generally capable of providing immersion protection, cooling, and cold weather protection. A shell may be designed for wear in cooperation with the liner. The shell may be capable of providing protection against flame, acceleration, and other environmental factors, as well as providing cooling and gear carriage. The disclosed integrated ensembles are generally low-bulk to facilitate movement.

Abstract: A body ventilation system for enhanced personal comfort. A gas distributor including a network of gas flow elements is disposed on a permeable substrate. The gas distributor defines at least one channel in fluid communication with the gas flow elements. The gas flow elements are configured to receive gas from a gas supply such that gas flows through the gas flow elements and exits to the channels substantially parallel to the surface of the permeable substrate. The gas from the gas supply may be conditioned. The permeable substrate may be a wicking material and may be a garment substrate. The gas distributor may be substantially incompressible. The gas flow elements may be selectively positioned to target the ventilation needs of a particular class of users.
