Each of your carabiners may only weigh a few ounces, but multiply that by your fifty cams and you're carrying a rather rotund child in 'biners alone. The DMM Phantom Carabiner 5 Pack trims the fat to help increase your efficiency for demanding traditional and aid climbing. The Phantom uses DMM's I Beam technology the spine resembles a steel I beam and a lightweight alloy for strength and weight reduction, and the custom bent wire gate pulls itself into the nose when weighted. A steep basket and a slight rope groove keep the Phantom loaded along the spine. DMM anodized each Phantom in the 5 pack in a different color to match your cams or to add a little rainbow flair.
