Great foldable reusable water bottle!
Great little packable bottle! I’ve been using this for three months now regularly. Zero leaks and I have not been gentle. Hiking, cycling, traveling, and everyday walking. The carrying handle loop is sturdy and feels secure. I added a small carabiner which has been extremely helpful for clipping onto bags. The bottle did smell plasticky when it first arrived. The initial washing got rid of most of the smell and after about two more uses/washes, the smell was completely gone. This bottle is super lightweight and folds up to nearly nothing, easily tucking into its own carrying loop. Refilling is easy. The bottle is not slippery at all, even when it’s wet. It doesn’t stand up on its own, but is small enough to hold with one hand and also hold the loosed cap with your other hand. When drinking out of the bottle, you have to either suck the mouthpiece like a straw or squeeze quite hard. If you opt to squeeze, be prepared for a turbo jet stream of hydration. That is the price you pay for security so the mouthpiece doesn’t leak when the cap is flipped open. Fair trade. This bottle definitely gets condensation on the outside if you fill it with cold water on a hot day, but that’s no fault of the bottle.

Great for skiing
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.

Super convenient
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.

Great, flexible water bottle.
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.

Perfect for Travel, No Leaks
This small water bottle fit well into my small pack on our European trip. Did notice some early "taste" but that faded after use. Really like how it sealed (no leaks at all), easy to squeeze out the water and that it packed down really small.

Good product, bought a second one
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.

Tricky to fill without spilling
Bottle quality: I like that its velocity can be used to flush wounds. I don't like that the lid often cross-threads. It's also a trick to fill in the field from a larger bottle (like a 2-liter Playtpus) without accidentally spilling/squirting yourself with it. I thought about returning it but I'm keeping it in case I need to flush a wound with it while hiking. I wouldn't necessarily recommend it to anybody, but I've not tried other collapsible bottles to compare features.

Great collapsible flask
500ml is the perfect size to toss in the pocket of your jacket while you’re doing outside things. Durable and good quality. I also like how they collapse as your drink from them so you’re not left with a bulky empty bottle. I use mine while skiing and have never had an issue with leaks or punctures.

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.

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。
