The history of shoulder pouches

Early uses and background

The prototype of the shoulder pouch dates back to ancient times. Paleolithic humans used the skins of animals they hunted to create pouches, which they used as clothing and carrying items. In medieval Europe, the Crusades led to the appearance of waist-hanging pouches (omonières) and small bags (pochettes), which are said to have become the prototypes of modern bags.

In modern Japan, at the end of the Meiji period, non-commissioned officers of the former army used "zunou" pouches to carry maps and documents, and heavy shoulder pouches with leather flaps were made.

As such, shoulder pouches were initially used for practical purposes such as hunting, travel, and military communications.

Material evolution

Initially, animal leather was the main material, but after the Industrial Revolution, materials such as canvas became widely used.

During World War II in Japan, restrictions on the use of leather led to various attempts to use alternative materials, including seal leather. It has been recorded.

In 1953, after the war, Toray released a bag made of high-quality nylon (Toray Nylon Bag), revolutionizing bag materials.

Recently, in addition to high-strength nylon and polyester, we have also started using recycled nylon, recycled leather, and our own "Kaminoito" thread. Sustainable fabric Eco-friendly materials are actively used.

In recent years, Prada's "Re-Nylon" collection ( Models made from recycled materials such as recycled fishing net nylon are also now available.

Design changes

Traditional shoulder pouches typically had leather flaps and clasps, but since the 1930s, zippers and Velcro fasteners have become common. Early pouches had simple storage and few exterior pockets, but modern pouches have improved storage capacity with multiple pockets and compartmentalized interiors. Straps were originally thin leather belts, but today wide nylon webbing with adjustable length is the norm, and pouches come in a variety of shapes and functions, including cushioned padding and chest straps.

Representative shapes and uses of each era

• First half of the 20th century (up to the 1940s): This period saw prominent military and government use. In Japan, vertical canvas shoulder pouches like the old army map pouches were used to store maps and documents. In Europe and the United States, leather satchels for officers and signal soldiers were also seen.
• 1970s-1980s: As outdoor leisure activities became more popular, lightweight nylon and canvas shoulder pouches became popular. New York bicycle messenger companies adopted standard color-coded shoulder bags, and messenger bag culture began to take root. Around this time, sporty designs and large logo bags also became popular.
• 2000s and beyond : Fashion brands have also entered the shoulder pouch market. Prada achieved a global hit in 1978 with its shoulder bag made from high-performance nylon, Pocono, and has continued to release sophisticated designs ever since.
• In 2019 , they released a shoulder bag made from "Re-Nylon," a material made from recycled fishing nets, and their sustainable collection, which maintains durability and water repellency, has become popular. Pouches with diverse designs are now available in a wide range of categories, not only from luxury brands but also from outdoor and street styles.

Diversification of modern uses

In recent years, genderless designs that can be used by both men and women have become mainstream for shoulder pouches. In terms of functionality, the increasing use of high-density nylon and water-repellent materials has dramatically improved waterproof performance. Security-enhanced models with internal pockets and key holders, as well as models for the mobile generation with dedicated smartphone pouches, are also on the rise. With a wide variety of uses, including business, leisure, travel, commuting, and cycling, mini bags using eco-friendly and high-performance materials, as well as simple and functional wallet pouches and smartphone pouches, have become increasingly popular in recent years.

That's why K-iwami's shoulder pouches are garnering attention as a product that stands out from the rest.
