At least both sides of your handle are sewn apart. Mine are sewn together, and you can barely get a finger in there. In place of the handle, I've just been picking the bag up by the top.
Another thing is some of my clips don't lock in the strap at all. Tighten them, and they are loose the second you move the bag.
I would like some drain holes in the side pockets if that's where the water bottles are to be held. If there are some, I couldn't find them. I would also like a little more room in the side zipper pockets. There's just very little room for anything but a phone.
