I know I'm not the only one that travels with a water bottle. Peer down the isle in economy as the flight attendants poor cups of water and you're bound to see a few water bottles being handed to them.
It just makes sense, on long haul flights you need to drink a lot of water to stay hydrated. Unless you want to be walking back and forth to fill up tiny cups with water or be constantly bugging the flight attendant for more water, your own bottle is the way to go.
Here's the problem with your average water bottle, when it's empty (which it should be when going through customs) it takes up more space than necessary. Enter the solution - The Que Collapsable water bottle.
Made from silicon, one push and twist reduces the size of your bottle to half. Not yet available, you can support the creators by backing the project on Kickstarter and order a bottle or two for yourself.
