SMALL SCALE 
1 strap, was working as a handle bag or a side sling bag but did not look right on body.
Backpack made a lot more sense as it relates to the body and the 'circularity' that relates to shapes.

FULL SCALE
As a backpack, 1 strap is tedious functionally, tried to strap around the body which works in a way but does not appeal for me.
Tried a particular zipper placement as a form of opening, length was way short.
The shape lacks dimension

Improved shape, the dimensionality is better.

Added a second strap to function as a backpack but still convertible to previous side sling arrangement.

Added a fully double zippered closure. and the closure basically acts as a the thing keeping the entire thing together.
Fully lined.

Things to be improved: straps need some sort of a interlining, probably hanging.

1+1=3
a sac that shares key design concepts. circularity, a product that struggles to be a product, no beginning no end
