Seriously, New Zealand must be a wonderful, wonderful place to live. And a product like this could only have been invented by a motorcycle touring fiend. Stick a metal canteen full of water under your seat/on top of the motor and when you need to stop for a break, squirt a bit of coffee-concentrate in your mug and add hot water.
I wonder how it tastes.
If you aren't familiar with Sandwich Girl's blog (how I found out about this amazing product) about life at McMurdo Station in Antarctica, well, you oughta check it out. No motorcycles, but damn interesting all the same.
