I bought one of these about a year ago. Since then I have stocked up in fear of them discontinuing the best bag ever. I have been using this daily. It fits basic necessities, extra diapers (for my kid not me!), umbrella, drink, tablet (no padding be careful), etc. It can be lengthened or shortened. I have added tri-glides and small black diamond plastic caribiners on each side of the strap to attach keys, drinks, etc. The side pockets fit Perrier bottle, umbrella, kids Nalgene sippy cup, phone, etc. It carries very comfortably as long as there aren't bricks in there. Love the fact that the bag itself weighs next to nothing. Buy this it will not disappoint. I own the black.
I have a slightly older version of this bag. It has held up well for over 6 years with almost no sign of wear despite using it EVERY DAY. I bought it as a gym bag and chose it because it is super-lightweight. I did not want to add extra weight to my daily carrying load when I already had to carry so much stuff! I've carried around a university campus and really appreciated its next-to-nothing weight. Has minimal but useful pockets. Washes well and air dries quickly. I wouldn't use this for anything too heavy or sharp (though it's pretty sturdy); it seems designed for clothes and other soft gear. Perfect gym bag.
