Metolius' classic ergonomic cut gives the user excellent freedom of movement while keeping the sling solidly in place. They achieve maximum comfort via laminated 600d polyester outer, die-cut closed-cell foam, and comfy Conlure™ lining. Custom CNC aluminum buckle allows full adjustability for all models and poly tubing over the clipping area of the sling keeps carabiners from hanging up. Innovative multi-loop allows for distinct organization of your rack and the Double-D attachment upgrades either sling into a double-sided gear sling.
