Trekker series - GIVI have ventured into the adventure touring market with the new Trekker series. These aluminum/polypropylene cases utilize the patented GIVI Monokey system giving a lockable, waterproof and easily removeable case option. The 33 and 46 liter GIVI TREKKER series are their newest adventure touring cases utilizing a unique full and partial lid opening system. The spacious 52 liter top case does not sport the dual opening system but does allow the storage for two modular helmets where the othe sizes do not. Made from a combination of polypropylene and aluminum panels, the TREKKER series with its patented MONOKEY © latching system now offer the convenience of GIVI hard cases in a more rugged style for the adventure touring motorcycle rider.
