Got this on Bonktown one day for 20 bucks, and it was worth it. Pack does exactly what the description says. The bottle is good quality and stays put, and the pocket holds keys, phone ipod, etc. Good for a 10K or a couple hours of light hiking. Pack will shift a little when running for a while or fairly hard, but for the most part stays in place once cinched down. If you need something just to carry a bottle and a couple of small items this is absolutely perfect. Got to say though the gel flask pockets are a little awkward, and I don't use the gel flasks at all, but seems like they might be difficult to get out on the move. I think they are made that way to keep the pack light and small.
