Messenger bag
bag or pouch with a long strap, designed to wear slung from one shoulder and across the body
A messenger bag (also called a courier bag) is a type of sack, usually made of cloth (natural or synthetic). It is worn over one shoulder with a strap that goes across the chest resting the bag on the lower back. While messenger bags are sometimes used by couriers, they are now also an urban fashion icon. Some types of messenger bags are called carryalls. A smaller version is often called a sling bag.
History
This design of bag has been used in the transportation of mail and goods by numerous types of messengers, including Pony Express riders, postal workers, messengers on foot (especially in ancient times), and bicycle couriers. Some Royal Mail carriers currently use large messenger bags to deliver mail in lieu of a postbag.
Pre-dating today's messenger bags described herein as specifically for bicycle messengers, fashion brands had been creating "messenger style" bags modelled after military map case bags and document pouches featuring a shoulder strap intended for wear across the chest for over a century.
Use
Similar in function to backpacks, messenger bags ensure comfort for people carrying heavy and/or bulky items, while allowing easy access to the contents.
They typically incorporate features that make them suitable for cycling.

Why this record matters
