The Perfecto is marketed as the iconic motorcycle jacket. There are two versions: the Perfecto 618 and the Perfecto 118. The two jackets come in the same style but have different sizing and use different leathers.
The Schott company was established in 1913, and first began manufacturing their Perfecto jackets in 1928. The design of the Perfecto 118 has undergone few changes since its introduction, although its cut has been changed a little to adapt it to the fit of modern clothes.
According to a Schott customer service representative, the Schott Perfecto 118 is made from "naked leather cowhide," a leather produced with no finish. This gives the 118 a matt appearance, and means that the leather is softer and more pliable than finished leathers. The leather is 1.2 to 1.4mm thick, or around 1/20th of an inch.
Marlon Brando wore a Perfecto in "The Wild One." Punk band The Ramones also favoured Perfecto jackets.
