    S25 - maximum HydroFlask size?

    Dear friends!
    If I want to combine a S25 and the centered bottle pocket with maximum sized Hydro Flask - which size of HF bottle can I fit?

    Thanks for answer!

    I regularly carry a 40oz hydro flask in mine, and the 24oz (which is taller/narrower) fits as well. But the 32oz is what it's supposed to accomodate and that's what I'd recommend. It really depends on how you have the bag packed, and I feel like the material makes a difference as well. I have a halcyon S25 and I'm not sure I could get away with as much if it were ballistic.

    There was also a slight change to the newer Synapse's center pocket that would probably retire my bigger bottles:

    I managed to fit nicely a 1L bottle.
    It's a tall and narrow one.
    Here is the link for it.

    Based on the shape of the bottle, you could possible insert a 1.5L one.
    You don't want it to be taller than the one I used. A little wider would work though.
