This basic style has been made by this company for many years now and there's a reason for it.  It has a roomy main compartment with a zippered closure and with an interior zippered pocket just the right size for a passport and keys when traveling.  On the outside there are two full width side pockets - one on either side - to keep easily accessible items such as cell phone, tickets, etc.  This is a wonderful light weight travel bag that can be used every day.  Worth the money.
