From the original garment design, there have emerged quite a few new parka designs that address special needs and uses, especially for the military. The U.S. Air Force, for example, designed the original snorkel parka (N-3B), which is a ¾ length coat with a full, attached fur-lined hood. The “Snorkel Parka” was so named because the hood can be zipped up leaving only a small tunnel, or snorkel, to look out of, and this protected the face and nose from the bitter cold. Critics said it limited the field of vision and hearing too much, but overall, it was well received, especially when the temperatures dropped below zero. The N-2B parka later followed and was similar, but it was a waist-length chicago cubs hawaiian shirt with an attached, split hood. These parkas were developed in the USA during the Korean War, mainly for flight crews subjected to -60 deg F temperatures. Originally, they were made with a sage green DuPont nylon flight silk outer lining and insulated with a wool army veteran hoodie type material. In the mid 1970s, the padding was changed to polyester wadding, which made the chicago cubs hawaiian shirt both warmer and lighter. Later, the outer shell material was also changed to a sage green cotton-nylon blend. During the Vietnam era, the parka hoods were changed from fur ruffs to synthetic furs.
In 1951, the fishtail parka was similarly used by the U.S. Army to help protect soldiers from the freezing Korean winters. Two styles of fishtail parkas were developed: the M-51 and the M-65. The M stands for military and the number represents the year it was standardized. The parka was named the fishtail due to the fact that the coat is longer in the back than in the front. This allowed the coat to be tied around the upper legs for added wind proofing. Neither coat was waterproof. The M-51 hood is integral to the jacket, but when not in use, it folds down inside the chicago cubs hawaiian shirt collar. The M-65 hood is detachable. Both feature a removable liner and are designed primarily for combat infantry and are to be worn over other layers of sweatshirt (lưới cầu thang). The fishtail parka, by itself, is insufficient to protect anyone from temperatures below 14 deg F.
Commercially, there have been lots of different modern parka designs emerge into the market today, made from a variety of synthetic materials. Some parka jackets are insulated with goose-down, Duraloft, Climeshield, or a number of other breathable and waterproof polyester fiber fabrics. Whether in the city, or enjoying the great outdoors in a rural area, parka jackets are worn by people from all walks of life who simply want to stay warm during the winter. Designers have used so many bright colors
There is a wide variety of modern parkas, with many different features, and they can range from several hundred dollars to several thousand dollars. The parka was not originally meant to be a fashion statement, but some of them look absolutely great, and are guaranteed to keep a person warm in most outdoor winter activities. Modern parkas were originally designed for the Yukon Quest Race and the long distance dog mushers. Worker’s on the Alaskan North Slope, and snowmobilers, also began wearing them, and soon parkas became a popular garment for all other winter activities, as well, because they can keep a person toasty warm when temperatures go down to about -30 deg F, or lower. The expedition parka design, in particular, will keep people warm in -50 deg F, -60 deg F, and even more extreme conditions. Most parkas have an outer shell that is often windproof, waterproof, breathable, and designed for plenty of freedom of movement while allowing layering of extra sweatshirt (lưới cầu thang) underneath. Some parkas have a mesh, or taffeta, inner lining which allows for maximum breathability and ease of sliding it on and off. Some have a drawstring waist and bottom, expedition cuffs, reinforced elbows, roomy raglan sleeves, and multiple zippered pockets. Most Parkas are machine washable. Some come with matching bib coveralls and gloves.
Buying the right parka with all the right features depends on its intended use, and some can be customized to meet special needs. There are parkas designed for mountaineering, law enforcement, fire-fighting, skiing, touring, and many other such specialty applications. For example, some parkas have battery-heated pockets, and inside cargo pockets for storage of temperature-sensitive items such as cell phones, radios, cameras, and similar electronics. Parkas are unbeatable for the most extreme conditions and anyone who works or plays outdoors during extreme conditions needs this jacket.
