## Description

Flexible bottles get an upgrade. The Flux is shaped like a hard bottle, compresses like a softflask, and cuts weight by 50%. Topped with a dust cover and twist-drink nozzle for grab-and-go hydration, plus a bail handle to keep hydration secure in your hand or on your pack. The Flux stands upright like a hard bottle but when you finish your drink, this bottle packs down to pocket size.

Review: Much improved over the previous generation, love that it stands on its own - I've tried a few soft bottles because there's a lot of appeal for camping and traveling - lightweight and doesn't take a lot of space, and sometimes I don't want to deal a hydration bladder. They've all had issues - nalgene's would fall over due to the large wide mouth cap, platypus's were impossible to dry, and so on. Found an older model of the hydrapak flux that I loved for camping and traveling - super easy to pack, came in at least 32 oz, stood up on it's own, and was easier to clean and dry. Didn't super love the twist cap as it didn't release air so it would eventually flop over as you drank, and the mouthpiece was exposed. After the wife made me carry her double walled bottle during skiing, I bought her bottle, and I feel it's been improved in every way. It's wider so there's a more stable base, they added a flip cap, and now when you untwist, it lets air escape so the bottle will expand back to it's normal shape. They added clear plastic on the top so it's easier to see how much liquid is left, and the cap prevents leakage while still in the open twisted position. The loop is longer which makes it easier to roll up as in the pictures, but it's still kind of a pain, so I rarely do it. I'm undecided whether to just steal my wife's bottle, or buy a second one for myself. I still use hard bottles for sizes about 32 oz as I'm unsure of the sturdiness of the larger sizes, but this has become my go to whenever I want to take some water out of the house.
Review: Used 2 at universal studios - These worked great at universal studios. They have free ice and water fill up. They do have a slight taste like your drinking out of a garden hose. But I also used it with a nuun tablet and the taste was gone. I also really liked the valve. It was easy to use and didn't spill. The fit in my cargo shorts, and I was able to carry in my belt. Definitely would recommend these.

### ⭐⭐⭐⭐ durable collapsible water bottle
*by A***R on January 18, 2023*

i've had several hydrapak products, and this one definitely lives up to the brand's quality standards. its much thicker plastic than my previous collapsible bottle that came with my katadyn filter (which this is also compatible with). this is a pro and a con for me. i appreciate the extra durability, and it's ability to stand up on it's own, but the extra bulk is felt in my hip pack... for short river hikes i really wanted something smaller and more easily crushable to fit in my little pack. like all the other hydrapak bottles and reservoir bags i've tried (and honestly pretty much all water reservoirs systems...) it does have a plasticy taste. it's not the worst, but it is noticeable. but if you want a collapsible water pack, that's just what you have to deal with. for most other hiking purposes, particularly if i'm carrying a backpack, this product is excellent! i think it will last much longer than my old .6L hydrapak that came with the befree, but im still sad they dont make these any more though.. hydrapak, if you're reading, please make a sub 1L softflask that is compatible with the katadyn befree!! thanks again for the great products!
