The MSIG Sled Dog Pack is a semi-flexible, aluminum load carriage backpack system with adjustable suspension. The lightweight design combines a vertically and horizontally mountable hole-pattern to fully customize shoulder, padding, load-out, and waist belt options. The aluminum frame balances robust load carriage strength with lightweight flexibility for movement. The pack's phantom profile is ideal for confined spaces and door clearance. Further, it's an ideal maritime carry system due to the minimal use of "nylon" and absence of a dump pouch to mitigate the system taking on water.
