The Flux is a lightweight drinking bottle with a spill proof twist cap that is versatile enough for trail runners, cyclists, hikers and everyday users to enjoy.

Hydrapak says:

Flexible bottles get an upgrade. The Flux is shaped like a hard bottle, compresses like a soft flask, and cuts weight by 60 percent. Topped with a spill-proof twist cap for grab-and-go hydration, plus a bail handle to keep hydration secure in your hand or on your pack. Finish your drink, and this bottle packs down to earn its space in your pack. With the Flux, innovation fuels performance.

Hydrapak's Flux Bottle 1.5L is a simple upgrade on the original soft flasks. The flask shape is great for packing in your pack or shoving into pockets on the outside. The twist nozzle has been changed and features a self-sealing valve making it spill proof so you're not worrying about it when its stowed away. The bail handle is useful for getting water from streams while the 42mm neck is compatible with numerous water filters such as the Katadyn BeFree.

The soft materials used in the Hydrapak bottles are great for keeping the weight down but most importantly the packsize is tiny once the bottles are empty. They are made with BPA and PVC free plastic and are good for a wide range of temperatures. They can be frozen too if you're in need of a particularly cold drink on a hot day.

I bought one of these for some serious hiking in Outback Australia, where water supply is critical. Less than six months after purchase, I was using the bottle in remote Western Australia when I discovered that the top corner seam had split, and I’d lost most of the bottle of water. Given it was more than 100km to the nearest source of fresh water, this could have been fatal. Luckily my wife had a metal bottle, and we were able to share her supply and make it back to civilisation. Hydrapak’s support was pathetic - they offered me an exchange but not a refund. Given this product has a severe design flaw and could have killed me, I do not want another one. Oh, and the water in the bottle tastes disgustingly rubbery. I washed it endlessly and even flushed multiple times with milk (as advised by Hydrapak support) and it never changed.

Tastes horrible

I've started using bottles rather than hydration bladders, having the bladder out of sight when I drink means I can't keep track of whether I've drunk enough or if I've nearly run out of water, as well as the fact the water always tastes nasty from a bladder. I bought one of these for when I need to carry a bit more water. I completely overlooked the fact that it's made from the same flexible bladder material! Well, the bottle is really nice, folds down small, is compatible with my Befree water filter, ace. But if you leave water in it for any short period of time it just tasted disgusting! Strong chemical, plastic taste. I initially gave it a quick clean and went for a hike. I literally spat the water out in surprise when I tasted it. I've tried everything I could find about getting rid of the taste because the bottle is great I'd love to be able to use it. I've tried scrubbing, bicarb with lemon (several times), freezing it, coffee, I've had it next to my sink to rinse and left it with water in every day since I got it (a few weeks now). Well its not made any difference at all, it still has a strong chemical taste if you leave water in it.
