Ya know how some girls are purse girls and some are shoe girls? I'm a purse girl. I've bought so many, reacting the goldilocks story with eery purse I buy. It's got a pocket I can easily drop my phone into, it's got a bit in wallet in the front compartment that opens so it's facing you and you can see all of your cards at a glance. It has a spot behind where the cards go that my field notes fits into perfectly and it has a pen loop. Hate being without my to do list. The only thing that would make it slightly better is if they moved  the pen loop a little to the right or left, would make it a little easier to get a pen into but I got a pen that's a little shorter than normal so it works well enough.
