Made of recycled ripstop nylon (super strong and lightweight fabric) the Topo Designs 16L Mountain Pack is an ideal travel backpack. It is very versatile and will allow you to roam the cities or the countryside in comfort AND style.
Inside you will find many compartments to store either your work stuff (because yes the Mountain Pack's quality will also please the buziness people) or your backpacking stuff (ideal for walking for several hours with food and drinks). You'll also find two external pockets (handy for storing a water bottle or an umbrella) and a zippered pocket at the top of the bag (to slip in your essentials like keys or a wallet).
In short, 16 liters of simple and light happiness, to take everywhere with you.
