We created the Momentum, our first soft-shell harness, 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 patent-pending Unity Spreader Bar for state-of-the-art connectivity with the included Unity Webbing Clips (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). *Spreader bar sold separately.
