Cool Tools- The coolest of tools

The instant I saw this, I knew I had to have one.  Colin was cool (what else could he be) enough to give me his personal one:

It's got a pressure gauge, pump and nozzle.  I've already started to think of the mods possible. What is it?  The Orbit Arizona Mist personal mister of course:

Why is it cool? 1. it is only about $25; 2. you can use it as a water bottle; 3. a few pump strokes get you minutes of mist; 4. it really works.

Orbit, a Utah company, has donated thousands of personal misters to troops in Iraq. On our ride over the weekend, one of the Posse members had an allergic/asthma attack.  I'm pretty sure that the mister saved the ride.
