VapurFlexible, Collapsible Wide Mouth Anti-Bottle with Detachable Carabiner, 34 Ounce, Blackout, Pack of 1

I often take a sling bag out and have a 24oz steel water bottle in it. Obviously it takes up a lot space and if I’m done with the water, that space can’t be reclaimed. This water bottle has more capacity in about the same size and when the water lessens, so does the space it takes up. The material is super durable and it actually does stand up when filled and even drinking it down to empty. Then you can just roll it up when you’re done.The cap is nice tight and I haven’t experienced any leaks. The flip up cap clicks in tight and is still easy to pop up when drinking. It’s easy to drink from, just like a sport bottle. No weird smell or taste either. Highly recommend this.

I haven't taken it on a trip yet but in trials at home this has lived up to its promises. It is very light and folds up small, totally leak proof from what I've seen although time will tell with use as the lid gets used more. I like that the capacity is more practical, other solutions I've seen only go up to like 16-20 oz and that's just not enough. My only complaints so far is that it's not easy to get water into the smaller hole if you have a larger flow of water, and I wish the carabeaner part was more flexible so that it can be hung and twisted more on a bag with less chance of breakage. But overall it's great and meets expectations, it doesn't alter the taste of water and I like that it sits upright when filled.

This is my 3rd Vapur water bottle for my family. We love them for air travel. Heads up the black colored bottle has no translucency, it's completely opaque. That makes filling the black colored bottle harder than the other bottles (which are see through).This review docks one star because one of the 3 bottles has had trouble with very slight leak (which surprised and disappointed me) but we made it work for the trip by using the clip to hold it upright in my backpack. Keep in mind the plastic (as all plastic does) will pick up scents (it still smells of perfume from the airplane and hotels).Yes they are harder to hold than a typical hard water bottle, but that's worth it for the ability to pack flat when empty. And they stand up well while holding water.

First off, let me mention that I've only had this water bottle for a day at the time of this review, but I'll be sure to update it as it sees regular use as I take it with me backpacking over the next several months.I wanted a water bottle that was light and could be rolled up when empty and stashed in a pocket, as lugging around an empty water bottle is always a pain as someone who likes to go out and about with just what's in their pockets and not carry a bag around. This seems to fit the bill. It weighs in at 43g (1.5oz), and rolled up your looking at max dimensions of about 5.75" x 3.25" by 2". Still a little chunky, but it'll go in a fair amount of pockets.I was hesitant to order at first, as I'd heard reports of leaks, and there at least *was* a known issue of leaks occurring even on brand new units when pressure like a squeeze is applied to the bottle and then any sort of lateral force is pressed against the cap or neck. I can report that the one I received, a 1L model manufactured April 2020, only exhibits this behavior if the cap isn't screwed on completely, which is a fairly easy mistake to make, so be sure to properly torque it on there to compress the o-ring that forms the seal.Otherwise, as a backpacker who likes ultralight and portable stuff, this is just about ideal. I'm looking forward to putting it through heavy use and seeing how it holds up!Do note: the blackout model at least is indeed a full blackout on the sides and not even partially transparent, so you won't be able to see how much liquid is inside. The bottom is clear... but that doesn't help much.

I used this while on a week-long European cruise and it was great to fill up on the ship and clip to my fanny pack or bag while walking around for our excursions. It is a flexible yet stiff plastic that when you fully fill it up it can stand up on a table, but when empty you can flatten it and roll it up or fold it up to stuff it in a bag for your carry on or luggage. I also like the cap since you can screw it on and off, and flipping the cap up to sip from it is easy. I thought the size was great as well. When fully filled up, it was enough to hydrate me for the several hours that our excursions typically lasted and was easy to refill at fountains.I think one note is that it's kind of awkward to clean. So I would recommend only filling this up with water. I've been just rinsing it with water and dish soap.

I'm a bit biased here because I love Vapur products, despite their longevity issues and the weird looks I get from people trying to figure out what it is. I've baffled more than one TSA agent. This black on black on black beauty is the best looking version they've ever made, and it comes in the Eclipse material!(!!!!) Maybe now it won't look so out of place when I bring it into conference rooms? My biggest regret here is that there is no 0.7L available on Amazon.For the uninitiated, Vapur has some huge pros and huge cons. They're much easier to travel with and much easier to lose than other water bottles. They don't flavor the water, but they don't stand up to abuse very well. They are super convenient, but they don't always conform to conveniences designed for normal water bottles. And even if you take exceptional care of them, they will inevitably wear out and fail you. For the right uses, they are totally worth it. Just don't expect them to work like other water bottles. They're better, and worse.
