Lug Puddle Jumper Wheelie organized carry-on bag, great gym bag with lots of compartments, a laptop compartment and more.
The best feature of this bag is that it has three carrying features. It can be worn as a back pack, or as a messenger bag or as a tote. The back pack straps hide away in the compartment in the back if you are not using them. So you an apply the long strap to carry the bag over your shoulder, or you can just use the great padded handles and carry it around as a tote. It's brilliant!
