The outstanding design of the Vector III secures all riser and pin cover flaps, even in the most radical freefall, without using Velcro. The main pin flap's closing, from the bottom up, protects the pin better, particularly while moving around in the aircraft and during freestyle maneuvers. The ergonomically designed harness curves over your shoulders nicely. It provides greater comfort and it fits narrow shoulders as well. The harness is also stronger as a result of improved confluence construction. The VectorIII has an over all cleaner look, a more protective design and a tailored and comfortable fit.
