I'm looking for a new pack. I don't go over a mile from my vehicle so I don't need anything big. I'd like to carry a fly box, couple of spools of tippet, nippers, floatant, leaders, a water bottle and maybe a granola bar. I also usually take my smart phone (for the camera) and some tp (for emergencies). I'm leaning towards the San Juan chest pack from fishpond but I'm not sure if it'll hold a water bottle and fly box? I'm also wondering if it'll fit? I'm not exactly petite at 6'4" and being much closer to 300 pounds than I like to admit.

Suggestions greatly appreciated,
