Bags. We all have them. But what's in yours?

What's in your bag when you commute to work?

I'm surveying anyone who has a bag and takes it to work. Why? I'm in design phase for a new rucksack for commuters. To help me make the next generation of rucksacks, please share the contents of your bag with me. Please.

The survey is available to take today and will remain open for anyone who finds it. Open to anyone, in any country.

If you want to give a bit more detail, visit the Google+ page to discuss with other commuters what the best bag could be.
