The DC-3V combines the best performance features of the prior DC-2, and DC-3 versions, while offering a unique internal visor to shade your laptop screen from sun and unanticipated field conditions. Twin compartments protect your laptop while allowing for peripheral connectivity from side to side. Best of all, the popular Portabrace Script and Tech cases have been redesigned as optional modules for the DC-3V for increased organizing efficiency and even higher value. Fits most 17" laptops.
