Doesn't shrink as you drink

Good bottle. Durable. Doesn't leak. What I don't like is the air is sucked back into the bottle after you drink so it doesn't get smaller as you drink from it. It remains the original size taking up too much space in your pocket. I prefer the Stow bottles for this reason.

Durable bottle!

I like how durable this bottle is, and how it rolls down for packing. It also stands up nicely on its own.

Packable Water Bottle - wash first

I've used it several times

The Hydrapak Flux 1.0L water bottle kept us hydrated on multiple day hikes, but it had a strong initial smell that required several washes to fade. The flexible material retained flavor, which can be a pro or con. The snap cap is convenient, but handle it gently to prevent wear. Even in cold weather, it performed well. It's lightweight, packable, and a solid option. They should add an option for a tube system for those looking to use it on backpacking multi day trips.

Perfect flask

I use the bottle every day, both at work and on trips. It is very convenient to hold in the hand, when folded it takes up very little space. I wanted to complete the flask with a plug-n-play cap and a hydra flex tube, but unfortunately there is no place to buy them in Ukraine:((.

Awesome bottle but the water tastes funny!

Fantastic product with one major flaw - the plastic used by HydraPak makes the water taste terrible. I've never experienced this from any other bottle or reservoir to this degree. I hope it fades out over time. I've tried soaking it with lemon juice and baking soda and it still has the foul taste. Otherwise, I think this bottle is incredible.

Great replacement for plastic

It's great - packs small, great for watersports and nice for the sauna where metal bottles would get too hot. The lid id a bit tricky, I also bought the straw lid but it's seems to leak with this bottle.
