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

This was a great travel accessory, I took it with me when I visited NYC and I hate carrying big bags around with me. Having a collapsible water helped me stay hydrated without feeling like I had to lug something around. I was worried it would get punctured or pop but I've been throwing this thing around and its held up so far. Cleaning it in a little awkward but you really just need to get the right sized bottle brush. I appreciate the simple design too, you don't really need to worry about mold building up.

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.

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.

Used it for 3 weeks while traveling. Great capacity. It was easy to fill up and never leaked. When full, it stands on it's own. The clip and roll up design were very convenient and helped with its portability. I didn't have any issues with a funny smell or taste. The only criticism I have is I should have gotten a more clear color shade as it can be difficult to see the water line when filling it up. Unsure of it's longterm durability but i would def purchase again!

The best water bottle I've ever owned. I own four of these (filling them before long bike rides and not having to deal with the waste of plastic bottles or the weight of hard bottles when I'm done with them), and they're just about perfect: light, collapsible, a built-in carabiner to clip to anything, 1L capacity, a wide-enough opening to fill from most spouts (and, incidentally, fit a Steripen into if you need to treat the water), and the most comfortable drinking spout I've ever tried. I get compliments on this water bottle all the time.That said, it'd be dishonest not to note that of the four Vapurs I own, one DID spring a tiny leak along a bottom crease. Not sure how that happened, and it'll be easy to patch, but the other three are holding up just fine.Oh, and for what it's worth, the blue is better-looking than the olive. Just my opinion, as the owner of both.

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.
