Just got this from a Mass Order seller in Singapore. The Vapur Anti Bottle. The idea here is that it is a water bottle but without the usual hard shell. So when it is NOT in use, it can be folded easily and kept in your bag or in your pocket etc. When you need it, it can be filled up and still be strong enough to stand. I think it is a great idea. I usually have a habit of bringing a water bottle almost everywhere but it can be hard to keep (when empty) as you need to squeeze it into your bag or carry it around like a small boy with a water bottle.
I guess it is also useful for people who can find a water source easily (e.g. in the office) and then bring it around and can then fold it up when it is empty. In fact, I even bring water bottle up to air planes so that I can drink in the plane. I emptied it before I go through customs and then filled it up again when I am in the waiting lounge.. (seriously useful.. I can really recommend you to do this as I did travel quite a bit)..
