The Tern WeatherTop Bag is the perfect bag for your Transporteur or Hauler Rack. It's a rugged and waterproof 45L carryall made to go from your rack to your shoulder in seconds (and look good doing it). Secure Fidlock® magnetic buckles keep the bag in place while you ride and are easy to detach. Roll down the top for waterproofing and extendable volume, or tuck the top portion into the bag to create a roomy toss-and-go bucket.
