No points for guessing how many ways this bag can be used...
The novel design means that the straps can be configured to wear as a backpack or switched into tote mode. This might seem somewhat useless but anyone who's ended up walking around a small or crowded store with a backpack will understand how much this would help.
A large internal space is complimented by external drop-in pockets for quick-access items like a water bottle or the ever-important phone.
