## Description

The Hydrapak Flux 1L is a collapsible, compact, and lightweight water bottle that expands into a rigid shape but compresses back down to save pack space. It's an upgrade for flexible bottles, mimicking the shape of a hard bottle, compressing like a soft flask, and reducing weight by 50%. It features a dust cover and twist-drink nozzle for easy hydration, along with a bail handle for secure carrying. Standing upright like a hard bottle, it packs down to pocket size once empty, ensuring ultimate packability in bags or pockets.

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.

### ⭐⭐⭐⭐⭐ Much improved over the previous generation, love that it stands on its own
*by F***1 on May 2, 2024*

### ⭐⭐⭐⭐ Compact, durable, but...still has a noticeable plastic taste
*by M***O on January 3, 2023*

I like that it's compact and folds up when it's empty - way easier to carry around than my normal stainless steel water bottle. I've used it for a couple months and the plastic taste is still present. I've sent their customer service an email and they replied promptly and gave me some suggestions that I tried and I still taste plastic. Customer service offered to replace it and I might end up taking them up on that offer, but I'd like to see if the plastic taste will disappear. But...maybe that's just what you get when you drink out of a plastic water bottle - I'll update in the future.
