The Karver II goes on with the concept of harness without shoulders inaugurated with the Karver. This concept has widely proved its potential in term of comfort, safety and handling. 
The Karver II becomes 35% lighter, more comfortable and simpler, but it becomes also modular, following the example of Kruyer II with whom it shares the system of fixation.
Indeed, Karver II is planned to welcome diverse modules. A reversible bag-airbag is already available. Some others modules will come later.
