Platypus Soft Bottle with Closure Cap

During my career, I have tested almost all sorts of drinking systems. This is the winner. Here you go : - Soft bottle: you cannot hold firmly a soft bottle, it's soft, you spill some fluid, and your clothes get wet. Platypus bottle is hard, you can hold it, and even place it upright, it won't fall. - Bladder: your backpack must always be half empty, else there is no room for the bladder. To refill, you need a mechanic it's so complicated. Then, surprise, it's empty when you are the most thirsty. - Hard bottles, even streamlined hard bottles are fine, but they don't accept a drinking hose, or, if they do, it gets mega complicated and prone to algae buildup. Platypus accepts the water hose.
Solution!: I carry 3 x 0.5l platypus bottles, two on both sides on the backpack, one in front, inverted, with a shortened water hose. Weight is evenly spread. It's easy to change the empty bottle without taking off the pack. Easy to calculate how much water is left. Easy to refill. Up to this date, no algae growth, and no discoloration inside. Useful and easy upgrade: I add a plastic S-biner with a cable-tie to each platypus bottle. Screw-on funnel - tarp funnels off a Hennessy Hammock fit to the platypus bottle perfectly. Much easier refill, you can even add a fishing line to fish the water from a stream.
