It is the dead stock of the carrier bag used to carry the US military medical kit (medical equipment) in the late 60's.
It is a popular item with little release from the US military.
The handles and straps give it a military-like ruggedness in terms of both practicality and design.
The wide opening is very easy to use and has plenty of capacity, so it is recommended for everyday use.
