>>2425812i bought a 3L bladder + 10L bag from AliExpress, $25 total. i use it for hiking and cycling and it's fantastic. held the hose in place with a couple velcro straps. genuinely easy to clean and fill. i've never used it for camping or for more than a day at a time yet, but i plan to soon. honestly i'm not really sure how it will factor in for camping, cause i still need to filter or boil the water first, but i'll see how it goes. picrel is what i bought. just search bladder and bag. i bought mine seperately from different brands but i think you can get them together.
