Compressive capacity of 1, water bag: we often need to be equipped with portable water bag bag stacking transport, even sometimes use backpack as chair, cushion for leaning on, even the bed to use. So using a no pressure product, the result will be very terrible. You will enjoy a wet trip. So I personally think, water bag must be at least under the condition of full water can afford to live a person's weight, otherwise it is easy to burst open. 2, selection of water mouth, water mouth of portable water bag is very important. Opening and closing, one-handed operation or teeth open when it's convenient. At the same time, also want to ensure the pressure resistance of water mouth is closed. Had seen a friend of a depressed water bag, water mouth closed is rather poor, so every time of transportation to pipe up, otherwise the backpack stack after water out of the water mouth place all the time. 3, inlet: obviously, the opening, the greater the water more easily, of course, the greater the corresponding openings the tightness and pressure resistance is the worse. At present most faucets are using similar to screw the mouth of the barrel lid as there are a few mouth water bag to use snap fastener water bag. 4, water bag hanging ring: many backpacks with water bag, but I suggest that if there are conditions will hang water bag as far as possible, so that you can avoid water moves back and forth in the package, increase the unnecessary energy consumption, the center of the transfer will be a little influence on feeling.
