Made to haul loads on our ARK Frame without needing a bag, the Load Sling is made from Xpac fabric which is not only incredibly strong, but also easy to clean up after a successful pack out. Three-quarter inch autolock buckles and straps feed through the holes on the side of the ARK frame and connect with a simple girth hitch. Each load sling comes with 4 straps, two connected to the top corners with male autolocks and a matched pair with Male / Female autolocks to go around your load. To attach to the ARK Frame: First, unclip the two upper sewn in straps with the loop on the end and pass the folded loop end through a side holes on the frame. Then, insert the male Autolock buckle on the other end of strap through that same folded end loop. Pull tight on the strap until the girth hitch is tightly attached against the frame. The 3-bar slider buckles at the bottom of the load sling panel will go into the slots on the frame located right behind the lumbar pad, or can hook into the bottom of the Shoulder Strap tracks (if open) if you need to get your load higher. The Load Sling can be attached to the ARK Frame and ride underneath any of our bags. Weight : 5.25 ounces
