The particularly large and wide opening allows easy access to the contents. It can be carried in two different ways: as a backpack or a travel bag (all straps can be stowed away when not in use). The durable and waterproof tarpaulin material offers protection from the elements and allows for easy folding for storage. Your items stay well organized in the inner mesh pockets. External compression straps effectively prevent the contents of the bag from sliding down when carried as a backpack. The padded bottom protects your gear when setting it down. Small items are securely and easily accessible in the lockable zippered side pockets (lock sold separately). Quick access to small items is provided through a discreet outer pocket.
