Leakproof, flexible, packable, and pretty - but after a few hours it adds a strong plastic/synthetic chemical smell and taste that makes me throw out the water. Will return item.

Makes water taste weird

I'm not sure how I feel about this bottle. I like how it packs away in small spaces with ease due to it being a malleable bag. It does have some structure as the top and bottom are more stiff than the sides are. You can keep it somewhat level when you're trying to pour into it. I don't like the flavor it imparts to the water. I wasn't expecting that. I have tried freezing with lemon water twice and leaving to thaw then replacing with filtered water. I'm kind of concerned about some sort of leach from whatever this thing is made from. For those concerned, it hasn't leaked and shouldn't leak by design - except for once due to my own user error when I didn't put the top on correctly.

Foul water taste

9 months ago

Size and form is great but water has a very strong rubber / plastic taste. Washed multiple times but it did not eliminate the foul taste.

Great!

6 months ago

I love it! Perfect for snowboarding and fits in my jacket pocket. I’ve taken a couple hard falls n it and it has never burst. The only problem is that sometimes the cap is hard to open, I had an older model that was a twist top, which was much better.

Stowable collapsible hydro flask

4 months ago

I bought this to keep Liquid IV hydro boost in my interior pocket of my ski jacket. It worked out perfectly in the cold and snowy mountains of Utah this March 2025. Very easy to fill and easy to use for a quick drink.

Thought this would be a great bottle for skiing. While leaning over to buckle my boots I compressed the bottle. The lid let loose and flooded my pocket.

good to save space

excels in packing, being soft plastic, which badly affects the taste of drinking water

Outstanding

I've been looking for a water bottle of this quality and convenience for a few years. It conforms to my backpack and is quiet which is important when I'm in the outdoors.

Fits in my ski jacket pocket!

3 months ago

Perfect for keeping water with me while skiing. It fits in my pocket very nicely and I love that it moves and flexes with me, and I can make it smaller as I drink the water.
