I originally got the Berlin bag as an early "mother's day" gift from my sister and mom and really liked that bag but I found it a little too big.  This bag is the *perfect* size for me.  The pictures do not do it justice.  The bag has two long narrow open pockets on each side which is perfect for sunglasses in a case.  Also the front pocket is amazing.  In the product picture you can see a very small zipper then a larger pocket behind it. That 2nd larger pocket is accordion like in that it opens nicely and has several smaller open pockets inside it including a built in credit card organizer that separates 3 credit cards.  The inside of the next size pocket has a spot for pens and a cell phone.  The largest pocket has several smaller compartments in it for organization.  The strap is sturdy and easy to adjust.  The bag is very well made and strong.  The zippers are easy to open and the contrast of colors from the dark outside to the light inside makes finding items that much easier.  The back of the purse has a zippered bottom and a magnet top so you can slide it over the handle of a carry-on when unzipped.  I keep it zippered and use it as an extra pocket for tissues and wipes that are quick for me to get to (I am a mom!).  I never was a woman who used a purse much but now I am because I LOVE THIS BAG!
