This is the new type I came up with yesterday.
I call it "mikazuki" bag, meaning Crescent moon in Japanese.
The front part is one pocket, so you can put any junk in here.
I love to put this side pocket with a lid. Velcroe makes it much safer to put things in it, and I always store my mobile in here. Very easy to access and easier to hear the bell.
I always shop light, so I only need this small size.
