These are wonderful products.  This is the third purse (Zip n' Go Slim)  I have purchased in the last 6 months from Baggalini.  It actually does what the catch title advertises.  I can fit everything I like to take in my purse and still have room and pockets or places to store more.  Still, the bag itself stays remarkably 'almost-flat'.  It is much less cumbersome than the other purses by other brands I have tried and subsequently discarded.
Furthermore, these bags are of a strong nylon fabric that cleans off nicely.  The interior is of a light color so it is much easier to find what you want.  Since purchasing these three purses (in different colors and some different styles), I have never gone back to any of my other ones.
