Great Bottle, recommend to purchase!
Yes , I recommend this product
Have recently purchased this bottle, and I absolutely love it! I used to have an old water bottle, exactly the same size, but it was so heavy and frustrating to carry around all the time. My father did research on which bottle would be the best, and came across HydraPack. I test tried it, and ever since, I refuse to switch to any another water bottles out there! It's very light, compatible, and the best magic is that it folds! I will be able to secure it around my belt, which will let me easily carry it. And the filter will keep me safe when it comes to drinking any water outdoors.

IT FILTERS SO FAST!
This is such a handy filter flask! I do have some of their other filter products and they work great and the flow rate is good, but I was surprised how easy it is to drink out of this one with the different cap. Super easy to fill and drink out of, and I don't have to spend time filtering water, I can just drink it on the go. Also the velcro straps are really strong, nothing slides or falls off, even when jog/jump (which isn't a lot cuz my backpacking pack is heavy, but still).

Works and stows easily.
Yes , I recommend this product
Works great and the flexible shape lets it take up less space. Used it for 2 weeks traveling across europe. I could fill it all the way up if I felt like I was going to be out longer or only fill it half way to save space in my bag. Wont travel again without this.
