HydraPak Stow Collapsible Water Bottle – 350ml, 500ml, 1L – Ultralight, Leak-Proof, BPA-Free, Filter Compatible Travel & Hiking Flask

This water flask is lightweight and compact, allowing me to carry some water with me on the slopes while skiing. It's a great size to fit inside my ski jackets, and is soft enough to absorb some falls without damage. I got the 500 ml, which I feel is a great balance between holding water without introducing too much weight. At 500 ml, it holds a little over two mini plastic water bottles, which is enough to last me the entire day on the slopes. The shape of the bottle is great, even when filled up it doesn't bulge out of my jacket much. The materials feel high quality and sustainable, and I feel this will hold up for many ski trips.

I was going on a trip and was unsure how available water would be during my adventuring, so wanted to be able to bring a liter of water if necessary, but didn't want to always dedicate bag space to a liter bottle. This is perfect because if you put in less water, it takes up less space. And since it's flexible, it fits in a bag much easier and also decreases in size as you drink. I also found it was great for the plane because I just kept it in my lap for easy access and it didn't roll away. Honestly, awesome. I kind of want to get the smaller one, but probably don't need it since I can fill the 1L up halfway. (Also, the 17 oz bottle is the same price as the 1L on here.) Mine tasted vaguely chemically at first. I washed it with dish soap and then froze it with lemon water, and it didn't make much of a difference. There wasn't time to try again before leaving, but over the course of my trip, the weird flavor disappeared. If the flavor had been really strong, I don't know what I would have done. Note: I saw a comment about how gross the mouthpiece gets and was worried, but it wasn't an issue for me. I used it for water only, and didn't really wash it during the trip (gross, I know) because the country I was in didn't have potable tap water. That said, after 13 days, the mouthpiece still looks clean.

I've been loving this hydrapak, been using it for about a year now. No leaks so far! It had a rubbery taste at first, but I washed it out with dish soap and hot water a few times, pretty thoroughly, and the weird taste has faded with time. Folds up real well and is great for air travel, hiking and skiing. Fits in the airplane seat pocket perfectly and I love being able to throw it in my backpack and jacket pockets without any issue. I actually bought a few and they made great gifts that I could fly with in my carry on. I purchased some carabeaners separately to gift with each bottle. My friend says they like to put theirs in the freezer for ice cold water! Love the squirty dispenser too - no more pouring water on my face! Just make sure to tip the water down into the cap when squeeze drinking so you don't squirt air in your mouth, it hurts!! And I like using it for cleaning when camping and need some water pressure. Knocked off a star because I find the cap difficult to put on, you have to thread it just right and the cap is not attached so it's easy to drop when filling. My friends have also complained about the rubber taste.

I enjoy the HydraPak bottles. I have owned one for 3 years and the 2nd one for 1 year, no durability issues to date. Very convenient for pockets of ski jackets and hiking jackets. Keeps your hands free and carries the weight closer to the body than a conventional bottle. Also like that they do not roll around, can place them on the car floor and boat deck and they stay in place so they are always handy.

Such a cool water flasks that makes life easier. Great value for the money. Extremely durable. I take them skiing and store them in the jacket. I’ve had no problems with leaks.

Super Awesome until it wasn't. I took it on my trip to nyc, it was the perfect size to not be so bulky and heavy when full, but kept me hydrated until I needed to fill up again. Also great that it gets smaller as you drink, so it's easy to stow or hang on your bag. However, it got a small hole in it in just a few weeks of using it, rendering it useless.. it is leaking water everywhere now. Maybe it got a faulty one? would love if customer service helped me out, then it would really be a 5 star product

We originally bought these HydraPak Stow collapsible water bottles for our Disney trip — we knew we’d be walking all day and didn’t want to lug around a heavy backpack full of water bottles. These were perfect! They’re super lightweight, easy to clean, and collapse down small when empty, which saved so much space in our bag. The twist cap is truly spill-proof, and the kids actually loved holding their own bottles, which made hydration way easier throughout the day. Whether you're heading to a theme park, hiking, or just want a BPA-free, ultra-light water bottle for travel or school, these are a great option. Highly recommend for families or anyone trying to keep their load light and stay hydrated on the go!

I LOVE this water bottle. It smooshes into any handbag or pocket and rolls up super small when empty. Doesn't leak. Thus far have used it walking the dog, going to work, and out sailing. My new go-to!

Una excelente forma de transportar agua, no pesa ni ocupa espacio cuando no está en uso, resistente y no le da al agua mal sabor o aroma .

Sirvió para viaje pero huele un poco a plástico.

Tras muchos enjuagues sigue sabiendo a plástico lo que la hace inservible

凍らせてリュックの背面に入れることで保冷剤としても活躍しました。とっても便利です。
