I just received it in the post today (thanks Gary) along with a crusader mug, crusader hanger, and water bottle and it is perfect for one day trips either away from camp/home.
You can fit basically all you need into it. Knife, sharpening etc, matches, water bottle, folding mug (found my one!), your billy (crusader mug and hanger), and some food. It's great!
I'll get some pics as i have just swapped my new digi taday for another one.
