I keep the MSR Trailshot squeeze filter in my daypack and a Katadyn Hiker Pro in my basecamp bag, and a Katadyn 10 Base Camp gravity bag.
I used Lifestraws for a long time, but honestly, I hate the ergonomics. Getting down close enough to the water source to use it directly is a pain in the @$$, and dipping your bottle into the source means 1) you’re stirring up silt as water floods into your bottle, 2) the source has to be sufficiently deep near the edge to accept your bottle otherwise you can’t fully fill, and 3) your bottle becomes contaminated and can’t be directly used any longer during the trip without the straw attached - which is a pain in the @$$ when stopping for a quick drink. I don’t like keeping a dirty bottle and a clean, and hate reassembling or dipping the straw into the bottle - so with the Trailshot, I just sit down by the bank and pump filtered water into my nalgenes. The Hiker Pro is a much higher volume and better pump for daily/nightly refills. In warmer weather, we try to live out of the Gravity bag instead of pumping. I grab a bag full of water each night with the gravity bag to have water for the following day - as much as possible, this is enough. I also keep an MSR 6L bladder on hand at camp as emergency volume. When temps are constantly below freezing, of course the bags stay home, and the pumps have to be even more carefully drained and dried each day. Living at 1300 feet and hunting above 10,000, I dry out like a prune, so I tend to target at LEAST 3L per day, preferring 4-5L per day, with more when the air is super cold and dry, or when exerting to haul the heavy food load in or hauling meat out.
