Owner contribution
This was intended to be a back saver after humping a Mini Trekker rucksack around for a while. It holds about the same amount as a mini trekker sized backpack but you have to be careful when packing as the bag is rigid and won't close when over packed. The zippers (have loops for a padlock) are chunky and robust but can be stiff and difficult to close. The bag comes with a multitude of straps and attachments - most of which I haven't figured out yet. The number of internal dividers is generous, though give us a few more of the textile ones! There are four decent sized internal pockets - which add to the profile of the lids and can make it difficult to close if overfilled. The nylon wheels look as though they could go a few miles with me. If the bag was a little bit deeper - just a little bit then I could fit a body with a grip attached. My own fault for buying off the internet and not double checking. I might be attracted by the next sized roller bag because of this and the extra space.
What works
Compact, roller, fits in airplane overhead locker. Includes enough straps to make a dominatrix drool.
Room for improvement
Not deep enough to fit camera and grip attached.
