I started running outdoors for the first time last fall to train for a half marathon. Before that, I'd always run on a treadmill and kept a water bottle in the holster. After a few weeks of my hand cramping up from carrying a bottle on my outdoor runs, I bought this and have loved it ever since. The straps stay put nicely, and once you have a nice tight fit, there's very little bouncing. The zipper pouch is plenty big enough to store keys, phone, etc., and even has a little pouch within the pouch for super tiny things like a tube of lip balm. The bottle is great, too, no leakage and very easy to grip and take quick drinks. Nice wide mouth for easy transfer of liquids and ice cubes. My only tiny complaint is that for small women like myself, the belt on the pack is a little long, so that loose ends flap around a bit if you don't find a way to keep them secure. I've taken to shoving them inside the pouch, and that's worked well enough. It's a very minor thing, and I've been short long enough to realize that products just aren't made for people my size.

I use mine for running a five-mile course with no water available. The belt, pack, and bottle all fit comfortably and don't interfere with running or arm movements (if positioned properly). The bottle is large enough to handle an hour run if I'm judicious. I only have two issues. One is that the belt clasp loosens as I run such that I need to cinch it up tighter every quarter mile or so. The second is that the bottle fits a bit too snugly in its 'holster,' usually requiring both hands to remove it without pulling the whole belt up to my ribs.

I had the Amphipod Full Tilt Velocity, and I did not like how it compressed my diaphragm when I had it tight enough to not bounce. The Camelback is much nicer with a wider belt and rides just a hair higher than the Amphipod so that when it is tightened it is more comfortable. The Cameback bottle is also much nicer, a standard bottle, very easy to get out and put in (no strap to put around the nozzle). The belt still loosens more than I like on its own, so I have to futz around with tightening it a little every minute or so.

Overall has good appearance/good quality. Especially like the bottle and its always open function. My complaint is that I bought this for longer runs, but within a quarter of a mile, it was already becoming loose and requires numerous re-tightening---have tried different things, but continues to loosen--seems like there could be something done (e.g. a different strap system) so that it would stay put.

Uses std water bottles, which I like; less hassle than finding specialized bits. The tightening system just doesn't want to stay tight, I ended up using a bit of duct tape on the strap where it feeds through the buckle, that jammed it up well enough! Takes a few runs to get used to, but works well overall! planty of room for gels, tums, phone, whatever you need for those long runs!
