Good Nozzle Design
I have a drinking problem, (yes, that old joke) I tent to accidentally spray water all over myself when I'm trying to do more than a few things at once. With the CamelBak Podium Water Bottle - 21oz, that problem is solved as their on/off nozzle system makes sure the water doesn't flow unless you want it to. The overall design of it is bomber as it's impossible to toggle from off to on by accident unless you really jar it in the right direction. Now, just to remember what it was set at if you leave it alone for awhile.....
