• No answer after 15 days, so I found the first two answers elsewhere: https://sectionhiker.com/mountainsmith-scream-55-backpack-review/
    -This review seems to say that the "side mesh pockets" ARE the water bottle pockets.
    -Yes, each front panel pocket has its own side zipper.

    -Unasked, but opinion given in above review: Max comfortable weight capacity 25-30 pounds, by reviewers experience. 35# according to designer, 45# according to mfg.

  • The second review link I gave refers to a more recent model year Scream 55 than the one STP is selling. Sorry. [I don't know how to edit my previous answer.]
