Review on WITZMAN Canvas Travel Backpack for Men and Women - Spacious Convertible Duffel Bag with Carry-on Luggage Capacity (A568 Blue) by Ashwin Worlds

Very roomy but not bulky. I was concerned that the shoe compartment would take up a lot of space, but unless you have basketball shoes, there really aren't any. Lots of compartments and a strap make them versatile. Good for a week long trip on your own (unless it's winter) if you pack well. I got it for that very reason (mainly for the shoe compartment) and it's a real delight. The canvas feels pretty solid and the combination of clips and zip on the outer pocket looks pretty secure too. Definitely worth the cost.
