Durable fabric, though on the stiff side. Positive zipper -- not flimsy. The handles are soft vinyl, but they look a little cheap because of the sheen.
Inside there are three open pockets on one side, one of which has an elasticized top, and there's one zippered pocket on the opposite side. The main compartment has a full zippered closure. The exterior has two magnet-closure side pockets.
The Ava Purse is plenty roomy -- more roomy than I need for a purse, but there are plenty of other larger purses one the market. What I like best is that it can be a practical, everyday purse; I won't feel like there isn't enough room and it can be tossed into the car or the gym locker without fear of damaging it or getting it dirty.
I ordered this in the Houndstooth style, but contrary to the photo shown on the site, there really isn't much contrast in the pattern. It oftentimes looks like it is solid black. The bright, high-contract lining (lime green, pink flowers) is fun, but I'm glad it's not more prominent (i.e., featured as an accent on the outside of the purse).

Finally decided to return this. I got tired of the cheap feeling (and slippery) straps slipping off of my shoulders -- and I have broad shoulders for my frame! Also, it turns out there can be too much of a good thing, and I mean roominess. This is just too large of a bag for me to use as a purse.
