Our Momentum went on a diet, too, dropping 10% of its weight through critical analysis of its components and replacement, whenever possible, with lighter, leaner materials at no compromise. The Momentum is still our best-in-class soft-shell harness, built for those riders who desire the locked-in fit of a Ride Engine hard shell but also want maximum freedom and flex. The Momentum offers the same scientifically shaped Lumbar Lock back support and fit via a molded internal support plate. The Momentum harness connects directly with our Unity Spreader Bar for state-of-the-art connectivity (although if you’re stuck in the past and want to use your old webbing-closure spreader bar, the Momentum does work with it as well).
