Armored textile jackets: Cordura left and fully ventilated right

An alternative to leather is clothing constructed of man-made textiles. These can offer improved weather protection from heat, cold, and water, and the increased utility these garments tend to provide in terms of pockets and vents. Common materials include high density (600–1000 Denier) ballistic nylon (e.g.,  Cordura) and Kevlar, or blends of Kevlar, Cordura, and Lycra; and often include waterproof liners made from materials such as Gore-Tex. In both CE marked (meets European Standards) and non-protective garments, localized protection may be provided by armor

2 Leather

There is a substantial difference between leather jackets made for fashion purposes, and those worn for protection, such as motorcycle personal protective equipment. Leather jackets designed for protective use are safety equipment and are heavier, thicker, and sometimes even equipped with armor, thus they are a practical item of clothing regardless of the symbolism invested in them by popular culture. A leather jacket primarily designed for fashion purposes would not be much protection in a motorcycle accident because of the jacket's flimsy construction. Motorcycle jackets often have more substantial zips, weatherproof pockets and closures, higher collars, and are styled to be longer at the back than the front to protect the kidneys of the riders from the cold while the rider is bent forward over the motorcycle.
