You'll want to take the Base Camp Voyager Duffel 42L from The North Face with you on your travels because it's durable and practical. It is made from recycled polyester with a water-repellent finish and can be carried like a travel bag or - thanks to the padded and stowable shoulder straps - like a backpack. The medium-sized Base Camp Voyager Duffel offers 42 liters of volume, a laptop compartment, a divisible and easily accessible main compartment and an external zip pocket for cell phone and passport.
