A cooling vest is a piece of specially made clothing designed to lower or stabilize body temperature and make exposure to warm climates or environments more bearable. [1] [2] Cooling vests are used by many athletes, construction workers, and welders, as well as individuals with multiple sclerosis, hypohidrotic ectodermal dysplasia, or various types of sports injuries.
Triple F.A.T. Goose. This coat checks all our boxes—super warm, waterproof, windproof, stylish—and is made from high-quality materials that feel incredibly luxe to the touch (like the plush ...
One advantage of air-cooled clothing is that it requires much less energy to cool people down than to cool down their entire environment. For instance, an air cooled shirt uses 4,400 mAh of power for 8.5 hours on the fastest fan setting, while an average central air conditioning unit uses 3000 to 5000 watts of power [citation needed]. In some ...

The Extended Cold Weather Clothing System (ECWCS / ˈ ɛ k w æ k s /) is a protective clothing system developed in the 1980s by the United States Army Natick Soldier Research, Development and Engineering Center, Natick, Massachusetts.
Free cooling is an economical method of using low external air temperatures to assist in chilling water, which can then be used for industrial processes, or air conditioning systems. The chilled water can either be used immediately or be stored for the short- or long-term.
Water jackets were used to cool the barrels of machine guns until several years after the First World War, but modern machine guns are air-cooled to conserve weight and hence increase portability. In a reciprocating piston internal combustion engine , the water jacket is a series of holes either cast or bored through the main engine block and ...
A ground source heat pump is used in winter to extract the warmth from the Thermal Bank to provide space heating via underfloor heating. A high Coefficient of performance is obtained because the heat pump starts with a warm temperature of 25 °C (77 °F) from the thermal store, instead of a cold temperature of 10 °C (50 °F) from the ground.

The first field jacket was based on a civilian jacket suggested by Major General James K. Parsons, for whom it was unofficially named. [2] Unlike the service coat, the material for the jacket was more wind and water resistant. A further reason for adopting a field jacket made of a different material was that shortages of wool were expected. [3]
