This is a pretty good bag.  It seems to be made of high quality.  The main pouch has adequate space for all sorts of uses.  It is nice to have all of the accessory pockets.  There are a couple of design aspects that do not make sense to me, though.  First, the clip straps on the sides of the bag have to be unclipped to open the zipper to access the side pouches.  It is unclear what purpose these straps serve, except maybe to attach a rolled up towel or jacket on the outside of the bag.  It would be nice if these did not interfere with the operation of the side zippered pockets.  My biggest complaint is the lack of rigidity in the main pouch.  There is a support liner that fits in the bottom of the bag, but it is weak and easily folds.  Therefore, when you pick up the bag by the shoulder strap, it just folds in on itself.  One more thing I would have liked to see in this bag is one of those liners that has pen holders in one of the pouches.
