Strap wrap-up system
Someday I came across a bag manufacturer who made some kind of strap wrap-up system. It is used to shorten the strap that isn't being used, but is only dangling along your waist/hips.
It was like this:
The right pieces can fold up, till the middle part. Then the top and bottom can "wrap around" the package of fold up pieces, so the unwanted strap is gone.
The only problem: I want to use this as an example for a school project, but I can't remember the manufacturer... Does someone know who makes this (patented?) system?
Thanks in advance,
