As always, Agilite knows just what I’m looking for and builds it to great quality. I just threw my typical camelbak in my collapsible pc pack - its fit being awkward and uneven - and not a month later I find Agilite’s SAPI Hydration Bladder on their website. Needless to say, I ripped the Camelbak out the day I got the SAPI Bladder in the mail. My only “gripe” is it’s just a tad (and I mean a tad) too wide for my pack which is sized to a JPC 2.0. But nevertheless, it functions as intended so I can’t even complain. Thanks again, Agilite!
