VapurFlexible, 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 is great for vacation when you're out walking all day without drinks nearby. It's great because I can hook it to the outside of my purse with the little hook. Once I drink a little bit, it fits into my purse. I love when it gets smaller as you use it. Once empty it hardly takes any space at all. I'm not really sure how to get it clean though. I only use water in it but I wish there was a good way to clean it.

This bottle was perfect for traveling. The only issue I had was that I dropped it once from ~3ft onto flat gravel, and the bottle broke. I considered fixing it with a patch kit, but wasn't sure if it would be safe to drink from. Disappointing that the bottle was so fragile, but still giving 4 stars since it's not very expensive.

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 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.

Ok

I've brought this on hikes and long overseas travels. It's so compact (that I lost one in a hotel somewhere and purchased a second) and its great when traveling light with just one backpack. I will buy another when this one gets lost or breaks.I can attach it to the outside of my backpack after filling it with water and it takes up almost no room in my pack when folded up. I've saved more money than the product costs by not buying bottled water when on extended overseas trips. I can load up tap water at the Airbnb/Hotel and hang it from my travel satchel that has my passport and batteries in it and not have to buy water when exploring a new city or even when getting lunch somewhere I can just drink from my water bottle if they don't offer tap water. Which works great in a first world country, maybe get a water filter when traveling 3rd world countries.

This works great as a travel water bottle...I enjoy filling this up at water stations in public places specifically airports. It works as described. Note the carabineer is trash...the weight of the water is too much for it and it will snap loose at some point...it really only works when it's half full or empty to wrap and store. I bought 2 because the first one snapped off while biking due to the weight and for the second one I just removed the carabineer. Need a bottle like this with a stronger carabineer attachment point.
