Cross-section of layers in space suit construction. An (Integrated) Thermal Micrometeoroid Garment (TMG or ITMG) is the outer layer of a space suit.The TMG has three functions: to insulate the suit occupant and prevent heat loss, to shield the occupant from harmful solar radiation, and to protect the astronaut from micrometeoroids and other orbital debris, which could puncture the suit and ...
A vacuum is the best insulator, but its use in clothing is impractical. Dry air is a practical insulator. Extreme cold weather clothing uses still dry air to insulate the body, [2] layers of loose air trapping material are most effective. The inner layers should conduct moisture away from the body.
Additionally, different fibres react to cleaning in different ways, and fabrics may shrink or stretch, which, if they are still attached together, may cause rippling and distortion in the lining and outer layer of the textile. [17] As with moving or working with dry pieces, the textile should be washed in a flat, fully supported position.
The purpose of the inner layer is to draw sweat away from the skin to the outer layers to make them feel warmer. If a piece of clothing does not transfer moisture well, it is not strictly an inner layer garment but simply a mid-layer garment. Wool has a combination of wicking and water-repelling properties [1] and is highly odour-resistant. [2]

Shelter can reduce the functional need for clothing. For example, coats, hats, gloves, and other outer layers are normally removed when entering a warm place. Similarly, clothing has seasonal and regional aspects so that thinner materials and fewer layers of clothing generally are worn in warmer regions and seasons than in colder ones.
The New York Museum of Science and Industry was established through a $2,500,000 bequest from Henry R. Towne, for the, "creation of a technical museum." [1] The newly created museum was initially on display on 40th St. with a Dr. F.C. Brown as its director. [1]
Underwear, underclothing, or undergarments are items of clothing worn beneath outer clothes, usually in direct contact with the skin, although they may comprise more than a single layer. They serve to keep outer clothing from being soiled or damaged by bodily excretions, to lessen the friction of outerwear against the skin, to shape the body ...
