Hydrapak Handheld Hydration Flask

Started leaking at the seems after 4 uses.

Bought this to replace 8 Oz. Costco water bottles I would carry when running to reduce waste. Love this product as it's reusable and when you finish it and collapses small enough to fit in to run shorts pocket. I would also use it to carry concentrated liquid nutrition when running. I'm giving it two stars because after 15 uses it started leaking at one of the seams. Maybe I squeeze it too tight when running Lol!? Hoping my warranty replacement lasts longer.UPDATE: HydraPak responded immediately to my warranty claim and shipped a new bottle to me which I had within 3 days of the warranty claim. I've changed my review to 3 stars as the customer service was excellent. I used the new bottle and so far no problems.

Couldn't be happier with these bottles. I purchased not to fill with water, but to fill with baby food, my preferred nutrition on long runs and rides. I was unsure whether or not the bite valve would be sufficient for such a thick mixture, but it works just great - I use it without the extender, just the bottle top. Easy to clean, too.

Too expensive for what it was and I didn’t realize it would be collapsable. I bought it to put in the pocket of a running belt. It is too squishy to stay there after the water level goes down.

I've purchased this bottle several times because I haven't been able to wait for a similar size. The bottle fits perfectly in my hand. Unfortunately, it leaks at the seams after a few uses.

Great concept but developed a leak after about 10 uses sitting in a jacket pocket.

I use two at a time for long runs (one w/ caffeine and one w/o). The whole system is great and you can squeeze the majority of the gel out without much effort.

Awesome flask, the 300ml is literally a hand palm size bottle

While the flask itself was perfectly fine, the item did not come with the long straw nipple attachment as is shown in the picture.
