How is the suit of the polar explorer

The clothing I used during the expedition to the North Pole belongs to the ECWCS family - The Extended Cold Weather Clothing System. Developed in the early 1980s at the Army Research Center in Natick Labs, Massachusetts, the first-generation uniform was supposed to warm American soldiers in extreme cold conditions down to -50 ° C.

The current uniforms belong to the last, third generation (GEN III), and manufacturers claim that it provides thermal comfort at temperatures up to - 60 ° C. Like any clothing designed to protect against the cold at extremely low temperatures, the ECWCS system has many layers, each of which performs its function. Layers can be combined in various combinations, which provides flexibility and allows you to maintain comfortable conditions in a wide range of external temperatures.

Full set

1. Slim Polartec Silk Weight Dry thermal underwear for moderate ambient temperatures. The set consists of t-shirts and underpants. Linen is combined with any membrane fabrics and warming layers of fleece.

2. Warm, moisture-removing thermal underwear from Polartec Mid Weight Power Dry for low temperatures. It can be used as thermal underwear, and as a base layer.

3. The warmed Brandit Thermohose trousers with a special cut providing freedom of movement.

4.Universal fleece hood for extremely cold temperatures with several wearing options (hood / mask).

5.Assault backpack, made of cordura with a waterproof inner coating, has two main compartments to the full depth and two additional compartments on the front of the backpack.

6. Boots Mickey Mouse - veterans of the ECWCS (GEN I) system, developed back during the Korean War. They turned out to be so successful that since then no significant changes have been made to their design. The boots are made of two-layer rubber with a layer of felt and wool. Equipped with a pressure change system when used in the highlands and in airplanes, they are designed for the temperature range from -10 to - 30 degrees.

7. The warming layer (sweater) from Polartec Thermal Pro, can be combined with any option of thermal underwear and membrane jackets.

8. A set of jackets and trousers made of windproof and water-repellent fabric with insulation PrimaLoft Sport (synthetic analogue of down) for extremely low temperatures.

9. Extremal Cold socks from 100% wool.

10.Xenon, waterproof tactical flashlight with krypton and LED light source.

The lowest layer is two versions of moisture-removing thermal underwear made of polyester materials (cooler and warmer, combined with a warming layer). The second layer is the base fleece (insulation). As an external layer at moderate temperatures and high physical activity, a jacket made of membrane fabrics can be used. And at extremely low temperatures and low physical activity, it is recommended to wear a jacket made of windproof and water-repellent fabric with a heater made of synthetic analogue of down PrimaLoft Sport.

The article “Non-freezing” was published in the journal Popular Mechanics (No. 1, January 2014). I wonder how a nuclear reactor works and can robots build a house?
