Ya I am never out without my Hydro, so everything goes in there, I would look into buying a cheap hydro pack before I spent money on a frame bag, but to each there own. I saw a 3L hydro pack at Wal-mart of all places, I believe the name was North 49, or something like that, actually didn't look like it was that bad of quality, the bladder and bite valve were good quality, the bag was avg at best, but still for $20 how can you go wrong, I'll stick with my camelback.
