Nylon is a generic designation for a family of synthetic polymers, more specifically aliphatic or semi-aromatic polyamides. Nylon polymers have found significant commercial applications in fibers (apparel, flooring and rubber reinforcement), in shapes (molded parts for cars, electrical equipment, etc.), and in films (mostly for food packaging).

Elastane fibres, better known under their trade names, Lycra and Dorlastan, represent a further high point in the development of man-made fibres. Invented in 1937 in Germany, elastane has properties not found in nature, the most important being an extraordinary elasticity. Compared to rubber, elastane has both greater tear resistance and durability and a tension capacity two or three times greater, at a third of the weight. Elastane is used in all areas where a high degree of permanent elasticity is required, as, for example, in tights, sportswear, swimwear, corsetry, and in woven and knitted fabrics. When stretched, it always reverts to its original form. Elastane thus is a prerequisite for fashionable or functional apparel which is intended to cling to the body, while at the same time remaining comfortable.

Softshell is a class of knit or woven materials, made from polyester and nylon, used to make technical outdoor clothing that essentially bridges the gap between waterproof hardshell jackets and highly breathable fleece jackets. They’re more breathable (but less water and wind resistant), more flexible, and generally more durable than hardshell materials, and more protective than fleece. Softshells emerged in the early to mid-2000s in outdoor activities like climbing and mountaineering—aerobic activities with dynamic weather conditions, where a highly breathable, somewhat waterproof, somewhat windproof piece of technical clothing kept its wearer  moving, dry, and warm.

The DWR treatment is the first line of defense against wet weather conditions and prevents the face fabric from becoming saturated. DWR is a polymer applied to the face fabric that creates microscopic pegs, or hairs, that protrude from the fabric. These pegs encourage the water droplets to band together and roll off, instead of spreading out along the face of the fabric and soaking through.

UPF stands for Ultraviolet Protection Factor. It is the amount of ultraviolet radiation that a fabric blocks.  It is the ratio of the average effective ultraviolet radiation (UVR) irradiance transmitted and calculated through air to the average effective UVR irradiance transmitted and calculated through fabric.

The YKK® is the world's largest zipper manufacturer. YKK® products use the best materials that are made by the most modern equipment and are mass produced under extreme quality control. YKK® was founded in Japan, in 1934, by Yoshida. In the early years, Mr. Yoshida's company carried his name; it was called Yoshida Kogyo Kabushikikaisha, or YKK® for short.
