The Ortlieb Duffle is a heavy duty waterproof travel bag, which can be quickly converted into a backpack by using the padded handles as shoulder straps.
The tough PS620C base fabric makes this a very durable bag, protecting contents from water and dirt. The long TIZIP zip allows quick and easy access to gear.
An internal strap compresses the volume and contents can be secured with a padlock.
A daisy chain on the exterior of the bag allows extra gear to be fixed or attached.
