Venturing deep into the jungle, hunkering down in the arctic, or traversing across Eurasia are all just another job for the Ortlieb Roller System 140L Duffel. This rugged bag offers waterproof protection and versatile traveling options to help it take on any travel, adventure, or expedition. 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 rocky trails 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.
