Mystery ranch hover pack 50 Details The Mystery Ranch Hover 50 packs take a unique MYSTERY RANCH approach in providing both these essentials for warm-weather hiking. Most other packs designed for warm weather integrate a full panel of mesh against your back, but our HOVER packs feature anatomically curved frame stays to create a ventilated, air-cooled back panel that levitates the load off your back minimizing back-to-pack contact and maximizing airflow without compromising our Load Carriage vision. With our new, articulated HOVER yoke and harnessing, much of the weight gets redirected to the hip belt for a cooler, more comfortable carry. 420D Twill Box Rip fabric and YKK zippers Asymmetrical, 3-ZIP design allows full access to gear 7000 series aluminum vertical frame and lumbar frame provide lightweight comfort and structure Minimal contact creates maximum breathability Yoke has pre-curved fit to hug shoulders, a separate aero-spacer Used but good condition
