Vapur Flexible, Collapsible Wide Mouth Anti-Bottle with Detachable Carabiner, Convenient, Portable Hydration for Travel and Outdoor Adventures, 34 Ounce, Night Blue, Pack of 1

When I fly, I try to stay hydrated, as this is a major factor in preventing jet lag, but I usually need every inch of space in my carry-on, so I don't want to carry a bulky water bottle. This bottle folds up flat, so it takes up almost zero room in my bag. After I pass through security, I fill it at a water bottle filling station in the airport. When I arrive at my destination, I simply fold it back up and slip it back in my bag. The material the bottle is made of is high quality and it comes in many different colors to suit anyone's style.

This has got to be one of the best collapsible water containers around! It is very thin but it can hold almost a liter of water. It has a wide opening but it also has a flip cap that prevents any spillage. When not in use, just fold it and it will fit anywhere in your bag. When filled up, you can hang it on your bag using the carabiner provided. As long as you clean it well before and after use, it won't smell, unlike others. It is very functional and helpful especially in those long hikes.

I chose the 1 liter size because I thought it would be nice to carry that much water if I needed and could always not completely fill it if I didn't want as much water. Why pay the same price for a smaller size right? After using it for a couple of weeks, I think I'll order the 0.7 liter to see if that size is any better.Pros:Overall, the design for this foldable and water bottle is excellent. When you're done with your water, it's absolutely easy to store and carry not to mention that its super light-weight to begin with so carrying this bottle isn't a chore. I have not had any issues with leaks. The flip-top cap seems sturdy and pours well and the carabiner clip is actually useful. I'm not sure if the matte finish makes it easier to hold as I have not used the other Vapur bottles without the matte finish.Cons:Why did this bottle not get 5 stars? First, it does not fit the cup holder in my 2009 Honda CRV. It might actually fit if the bottle isn't completely full and I squeeze the base a bit to mold to the cup holder. Same issue when I'm at the gym. If completely filled with water, the base doesn't quite fit the cup holders on the elliptical or treadmill. I haven't used this for running because this doesn't seem like the best choice if you have to hold the bottle in your hand. They edges are slightly sharp and uncomfortable if you're used to a rounded water bottle and since the shape can shift, it makes one handed use difficult. I find my self having to stop while on the treadmill or elliptical in order to actually use the bottle. I'm not sure if the matte finish is easier to hold, but I do know that it shows scratches easier. Not a problem for most people but there are those that do not like seeing scratches on their belongings. Also, I don't like the placement of the carabiner clip on these flip-top bottles. I can't seem to manage to roll up the bottle and use the clip as easily as it's displayed in the images. It seems like the carabiner attached to the side of the bottles without the flip-top cap would make it easier to roll up and use the carabiner to keep it rolled up.All issues aside, this is still a great anti-bottle water bottle. I would highly recommend it and it is currently what I'm using when I'm not actively training or running outdoors. I prefer this bottle for commuting and even the gym because when I'm done, it's super light to carry and easy to stash.

I originally bought the smaller .7L at Whole Foods and fell completely in love, so I had to get two of the 1L.The colors are gorgeous and unique. They are not the same as the standard Vapur bottles and something about the 'matte finish' makes the color richer and more complex - it shifts as you move them around under the light. Like the skin of a sea creature. As photographed, they are more-or-less a (semi-opaque) warm fatigue green and an almost green tinged midnight blue, right out of the Crayola box.These are very sturdy. I've rolled them up a million times, tossed them at the bottom of bags full of equipment, frozen them and basically put them to hard use. They still look brand new. They never leak or pop open.You can bring a bottle of water with you and be relieved of the dead weight once it's drunk. They take up so little space that it's not unreasonable to stick one in your purse or camera bag. If you need to, you can hook them to the exterior of your bag and they don't flop around as obnoxiously as you'd think, because they're flattish and the plastic slides around smoothly. The carabiner also makes them easy to loop onto a finger when your hands are full. (That seems like a dumb remark, but they seriously are more comfortable to grab than SIGG or Nalgene or anything else I can think of.)The real reason I love them is that they are SO pleasant to drink from. It's like you can pour the water right down your throat. I've never been a fast swallower, but with these I can rehydrate zoom zoom. So, even when I'm at home, I prefer to use these. All my metal ones have been relegated to fall-backs that only get used when these are waiting to be refilled. They can even stand up nicely when they are empty, even though I usually prop them in a pot when I am piping distilled water into them.

Great ! Got this to travel to Europe. I wanted a travel drinking bottle that I could store as compact as possible.I weirdly like to taste the water in other places. This bottle has zero added taste to it. Iceland has my favorite water next is probably Norway. (So far! )I hung this outside of my backpack most of the time. It works great. And it is a great price (I wasn’t worried about losing it etc.)

I like that the water bottle can become compact and does not weigh a lot. However, it's hard to clean and difficult to fill up. It doesn't seem to be able to fill completely.
