I was hoping this wouldn't be one of those flimsy bags because that pretty floral pattern wouldn't let me leave this alone.  It's flexible but it's sturdy so even if you don't fill the bag to capacity, it still keeps it's shape.  That's the first good thing.  The second - as I said, the PATTERN with the flower is just gorgeous.  Third, I love that there is a over the handle strap so you can throw it on top of your suitcase and it doesn't slide down to the ground.  It's a spacious bag but it's compact and rests right on top evenly so the suitcase itself doesn't tip.  The material is a kind of nylon but it's the kind you can wipe down.  It has 2 zippered side pockets where you can store  your quart size bag of liquids upright and 2 zippered front pockets where you can put your wallet and travel docs.  Now, the final pro about this bag... it holds a TON!  Just as a test, I was able to put 5 sweaters, 4 pairs of pants, 2 sweater dresses, 2 nightgowns, a pair of sweats and 2 blouses and fit 2 Word Search puzzle books on top of it all (see pic).  Got this for my mom but am probably going to reposes it after her trip.  It's the perfect underseat/boarding bag or even a weekender or an overnighter.  Even my daughter wants one.  Don't think twice or debate, it's definitely worth the price.
