Hello! I realize that hydration bladders aren’t terribly popular here, but I’m hoping that you can nevertheless help me brainstorm some solutions to one of the reasons folks have ditched the bladders in the first place – filling them up without unpacking/repacking your backpack!
I don’t mountain bike or run ultra-marathons, so the “drinking on the go” aspect of the bladder/hose system is not its main advantage in my eyes, though it is somewhat convenient. Rather, I like that the system keeps the heaviest part of my pack where it belongs – snugly against my back! I have a 3L platypus hoser system.
I’m thru-hiking the PCT this year, and believe that for some of the desert portions I will be carrying 6-7 liters of water at a time. I have a 3L Platypus Hoser, a 2L Evernew bladder for storage, a 1L widemouthed Nalgene (for measurements and for drink mixes), and a few assorted soft bottles for the driest sections of the trail.
Where I need help: Previously I’ve used a filter to treat my water (Sawyer Mini), and by using a Quick Disconnect and a Fastfill Adapter, I’ve been able to squeeze-filter water directly into my pack without removing the bladder. This works great, except that I’ve come to loathe squeeze filtering. I bought a Steripen and love the ease of use.
I would like to ditch the filter in favor of the Steripen, but I’m scratching my head about how to get UV treated water into my hydration bladder without unpacking/repacking. Scenario: I’ve filled my Nalgene (might instead opt for a wide-mouthed Nalgene Cantene, or a Gatorade bottle, but for now this doesn’t matter), and I’ve treated it with my Steripen. I’ve got a long, waterless stretch ahead. How do I go about getting the water from my Nalgene to my other water storage bladders (most importantly, the hoser bladder that would require me to unpack my whole pack)?
The best I can come up with is to take the treated Nalgene water, carefully pour it into my 2L Evernew Bladder (funnel?), and then somehow use the Fastfill to squeeze the water from my Evernew into my 3L hoser bladder. This has the annoying property of reminding me of my squeeze filter, but without the actual filter resistance, shouldn’t be too taxing.
Any ideas about how I can treat my water for five months without hating the process (as I’ve come to do with the Sawyer Mini) of transferring my Steripen-treated Nalgene water into my 3L Platy hoser? I have a few chemical tablets in my emergency/first-aid/repair kit as a backup, but I don’t have any interest in using chemical treatments as my main method. I want to use UV treatment while still using a hydration bladder. I have thought of ditching the hoser, and just carrying a 4L Dromlite in my hydration bladder sleeve (therefore meeting my main objective of carrying heavy water next to my back), but this still would require that I remove the Dromlite when I want to fill and drink from it. So I think I want to stick with my 3L Hoser supplemented with my drink mix water bottle, and non-hose bladders for waterless stretches.
Help me, mad scientists / Rube Goldbergs!
Thanks!
