Just wondering what the latest thoughts are on hydration backpacks. I was originally looking for something I could just stash a little bit of gear in for downwinders/exploring, but figured a hydration bag could be good - so now looking at those.

I saw this one the other day which looked OK for $55 and seemed to have pretty good arm clearance. Some of the camelbaks seem a bit tight up under the armpit.

Anyone got one, or a better suggestion? How well do they last if used in the water 2 or 3 times a week? What should I look out for?

Thanks
