The durable and waterproof canvas fabric provides protection from the elements and allows for easy folding for storage. Your essentials stay organized with internal mesh pockets. External compression straps effectively prevent the bag's contents from sliding down when worn as a backpack. Padded bottom protects your gear when set down. Lockable zippered side pockets keep small items secure and easily accessible (lock sold separately). Quick access to small items through unobtrusive exterior compartment.
