Made to handle your roughest journeys and grandest adventures, the Ortlieb Roller System 85L Duffle Bag goes just about anywhere you can. Waterproof construction keeps your gear dry through tropical downpours and mountain snowstorms, and a rigid aluminum floor plate with foam padding protects against dings and dents. The heavy-duty wheel system rolls easily over muddy roads and cobblestone streets alike. Instead of giving it a telescoping handle, Ortlieb opted for an adjustable grip that offers plenty of leg clearance and a comfortable grip that you can fine-tune to your size. When the road gets too rugged for any wheel system, removable, padded backpack straps let you throw your gear on your back and carry on.
