| 1. First we need to know how much water we need and how much we can carry. - water bottle volume is chosen depending on: what activity you are doing, duration, length of the route and if on the route we have other sources of water or not. 2. Shape and design - flexible water bottle are useful because they help you to save space and fit easy in small spaces. You have to be very cautious because this bottle can breaks and if you carry them on your backpack you will wet everything you carrying (try to put them into separated dry sack). Also the flexible water bottle are very hard to handle and to fill them. - the rigid water bottle are available on these shapes: square bottle (take less space on backpack) and round bottle (fit very easy into backpack pocket). - the opening of a water bottle are in many size like: - wide mouth (you can fill it very easy and quickly, you can use ice cube) - narrow mouth (the content of the bottle don't flood so rapidly if tipped) - push-pull valve (id very easy to use, you have to pull to open and push to close) - bite valve (attached to a straw-styled tube, the valve is automatically closes after every use) |
