The Bootlegger series is a modular pack system for every adventure. The patent pending modular Super Tramp suspension allows the user to swap the suspension to different packs depending on activity or weather. One suspension and three packs, it's that simple.The design team at Boreas has introduced various packs, all incorporating simplistic, technical features sparing unnecessary hardware. They took this philosophy a step further and created their patent pending modular Super Tramp suspension. With the pull of a strap, the backpanel easily converts from a high ventilation trampoline suspension to a conventional high stability suspension.
