U don't want this model because it is cheap and just clipped together at the op and isn't a whole plastic bag.
U also want a quick release valve at the bottom, which this seems to have.
But you also want a bite grip at the mouthpiece, NOT a cap and an open straw with a push/pull valve like this model has. That was leak water if you don't have the cap on and recapping it every time you want to drink gets annoying fast.
I use multiple 3l hydration packs.
On a 9 hour hike I did last month I went through about 4 of them (3L bladder packs).
I brought 2 and refilled using a pump-action water filter (i.e. not a sawyer mini or a life straw etc), JoyPur brand, no name cheap Chinese brand, so I drink in total almost 12 liters of water on that hike.
>>1617371Paying for brand names is some retarded goy shit. Find what FEATURES the MSR guardian has that you like, then find a generic Chinese version on Amazon that has all the same shit from the same fucking factory even probably, at a lower price with some made-up Chinese brand name you've never heard of.
Why waste money?
