The vest is very good quality, and has enough space in the front pockets to fit the full water bottle in one side, and my phone and 3 gels in the other. The back pocket is handy for anything else that required.
My only drawback with it is the bottom clip feels a bit too tight around my ribcage, so I run with only the top clip done up. It feels fine once running, but would be better if both could be done up. For reference, I'm a 34in chest. It just needs a little bit more slack in the side elastic bands and it would be perfect.
