SCS™ - Super Compression Suspension:
This patented design attaches the shoulder straps to the OUTSIDE edge of the pack so the load is pulled in and held securely against you. This gets the pack's center of gravity as close as possible to your own. This load-trapping design allows the pack to follow your movement without hesitation, no swinging, no bouncing. And best of all, with our patented design, you don't have to crank down the waist belt to the point of risking kidney failure to get that kind of control.

SCS™ pack's low center of gravity, along with their no-bounce design, make them feel virtually weightless.
