Drinking bottle/coffee cup

[Revsi75]

Guys,
I just got myself one of these...
It's the Oakley Tank water bottle http://uk.oakley.com/products/oakley-water-tank-20-oz/99171-010

It's basically a stainless steel water bottle that can be unscrewed into 2 halves for storage. But you can use the bottom half as a coffee cup instead of carrying an extra one in your pack.
One thing is that you will need to find something to wrap around it to hold. I used a part of my foam roll mat as I cut my one to suit me, then held it on by a couple of cable ties or you could use elastics.

Great little innovation that has an extra use
