The family of Cotopaxi Allpa Collection Adventure Bags knows what they’re here for. Designed to make your adventurous travels easier than ever, these rugged, organized, comfortable, and nimble bags do the trick. These travel backpacks are available in six capacities, including 28 liters, 35 liters, 42 liters, 50 liters, and 70 liters. And the cool thing is that Cotopaxi states how long each adventure backpack should last you. The smallest size is good for a one-week trip, while the largest colorful bag can work for a trip up to six weeks long. Additionally, these Cotopaxi backpacks manage to maintain light weights, as the largest is fewer than four pounds. When you’re backpacking South America and carrying your bag all day long, that’s an important feature.
