I don't entirely agree. Being able to use a good squirt of water is a luxury I would not want to give up. I have done my time being sparing with the water, not any more. Espescially this hot weather.
Other than that, backpacks are great, just a shame about the batteries.
Agreed. Instead of people being happy with how little water they use they should think about turning up the flow up, because the lower the flow the lower your potential speed can be. Takes time to realise that though, takes time before you realise as well that what you once thought was the fastest you can go, wasn't actually the fastest. Especially with hot you can go much faster. Higher flow helps a lot. Trigger combines best of both worlds, great flow but still water saving.
But I do realise some people do need to worry about water meters and such as well.
