Details OMM Phantom 20 Vest Pack A stable, durable and roomy vest pack, for runners going the distance. The Phantom uses a 7 point harness to align the pack with your spine via a yoke behind the neck, so your shoulders are free to extend without losing energy. Two shock absorbing suspension cords over the shoulder work in tandem to further reduce swing, keeping the pack in line with the spine. Dual lower straps form an anchor to prevent pack bounce and hug the pack into the lower spine. The next evolution of comfort and stability for runners.
