Love this! It is tricky to drink from with a single hand but it doesn't bother me at all. I have it on my bag all the time, it is SO convenient! My mom loved mine so I got one for her too and this is now my "to go" gift for friends!

These are great for travel. They fold small and light when empty. When full they holdTheir shape and are easy to drink from.

So far I’m liking how compact and lightweight this water bottle is. I use mainly use it at work and easy to carry around with a carabiner attached to hang it on my backpack. The bottle doesn’t collapse even if it’s a quarter full. What I don’t like about the bottle is that it has a plasticky smell when drinking the water.

I have both sizes that these come in, amazing bottles. As an avid camper and Scout leader I'm always on the go at camp. I added a carabiner to mine so it clips onto my belt loop. I can go from station to station, fill it up and when emptied between water points I can pack it down to almost nothing.

I got this bottle to have in my bag while traveling for an extra bottle. It worked great. I enjoyed that it took up a small space in my bag. The sides were a little flimsy were not filled with water, but it worked out fine. I wouldn’t make this my every day water bottle but when you’re traveling and you want to have an extra or you have limited space this is perfect

PRO: As advertised: collapsible, portable, convenient.CON: Does not insulate well so expect lots of condensation on the outside. And freezing if used in cold weather. I had the bigger version of this which eventually tore at the seams after a month of use/abuse.RECOMMENDATION: Recommended for travelling (domesticated, like airport travelling, not rugged like hiking) for its portability.

It stands up even when empty, all other collapsible water bottles I had were falling all over when empty and in some cases almost had to force the water into the bottle. These also made it through the summer and a beach vacation, would consider them durable. Excellent purchase!

I like these bottles for travel. Light weight. Collapsible. Don't leak. Perfect size. Won't break when dropped. I will fill one up with filtered water, then, for extra protection, use a SteriPen to sterilize the water. Good for CPAP and other medical uses. My one gripe is the lack of instructions. The bottle can be compressed into the two end caps, which are then snapped together. It arrives in this condition. But unsnapping the two plastic end caps, which should be straightforward, is anything

This is a great innovation that we have used this summer while hiking the national parks. The plastic taste did not bother me, but some people did notice it. Hydrapack backs their product 100 percent, so if you have issues send them a picture with the problem and they will take care of it. The customer service is amazing. Support this company and don't buy Chinese knock offs. This is not a paid add, I have been using their products (i.e. bladders, hydration systems) over 17 years.

I bought this "new” version after my other one’s lid cracked when I dropped it. Despite that- these are durable AF. My last one made it to 3 continents, multiple festivals, and the top of Kilimanjaro so I was gutted when the lid crapped out on me. I expect the same durability with this one-the handle is WAY better than the old one, and the mouth is wider. It folds down and fits easily in a bag or cargo pant pocket and can clip on to a backpack (though I’d only recommend that if it’s empty)…

The Hydrapak items are nice to have and pack up nice and small when not in use. The soft sides make it a little difficult to drink from. They are really nice space saver when empty and being packed away. I like to use them as a spare water container to refill my normal bottle to drink from.

This product is greate for taking water for your dogs or extra if you feel like you need more. Its also a sllim lightweight option for the airport. Just becareful drinking from it because as you drink water the structure starts to collapse. The cap seals very well and it has survived a few drop tests.

no leaks, no spills, no plastic taste. takes up very little space when empty. i do wish that the cap had a leash. I have looked for a sip or straw cap and have not been able to find one.

I am fairly good about drinking water throughout the day as long as I have a bottle near, but have always hated lugging around an empty bottle once I was done. I saw this on a trip to Yosemite and have been wanting it ever since. I love the idea of squishing it down and throwing it in my bag w/o taking up any space.First impression, I was worried about how flexible the material is, but I've taken it to the gym a couple of times and it's great. Filled, it doesn't spill and stands up like a…

It’s an awesome bottle and would work great for backpacking where storage becomes critical, however, it takes two hands to drink from and proved to be a little tricky 90% of the time…

I spit out the water the first time I drank from this (yes! I washed it first). I washed this five times and never could get rid of the taste. It's a very strong plastic taste. I had two other people try the water without warning them of the taste. Both had similar reactions and found the water undrinkable. It's quite disappointing that this product is advertised as "No weird taste" yet is one of the foulest tasting water bottles I've ever purchased. Needless to say, this bottle has been…

It's super convenient and easy to use. The big problem is the plastic-y flavor it gives to water. I washed the bottle before first use. I never leave water in it for more than a few hours. Technically what I'm sensing could just be the smell, since it's hard for our brains to separate the two. Either way it kills the experience of drinking from this bottle.

Took on a trip to refill smaller, rigid water bottle. Poured easily into the smaller container. Think it would have been fine drinking straight from it but was going for easy. Folded away quite well and easily. Does take some time to thoroughly dry out but not a biggie. Would recommend and buy again.

A good collapsible bottle. I wish I would have gotten the larger size. The only draw back at first was the plastic taste which took a while to wear off even after washing.

This is a great option if you’re a long distance backpacker and want a pee bottle for use at night so you don’t have to leave the tent.
