Butler Creek Sling - Its stretchable construction and soft padding soak up the bounce you get with traditional slings - reducing felt weight up to 50% - so even the roughest hikes are smooth on your shoulder. Soft, flexible closed-cell neoprene with Comfort Stretch backing. Dramatically reduces felt weight. Non-Slip Grippers keep it firmly in place. Available in popular camo patterns, with or without Uncle Mike's QD(R) Swivel sewn-in.
