A couple of years ago I went to Brazil for a month. I took a backpack. One of my friends took Country Road duffle, which is like a durable clown car for your clothes because impossibly enough, it fit enough stuff for four weeks. And it's much better looking than my tattered knapsack.
At $US60, these totes are a steal, because they last. Every time we've traveled together since, he's brought his Country Road along, whether it's just a weekend trip or a longer journey. [Country Road]
