The CaldwellA(R) HP Neo Sling's ergonomic shape is designed to spread the weight of the firearm for a comfortable carry. The neoprene design of the material grips your shoulder so the firearm stays put and stretches slightly to cushion the firearm as you hike through the woods. If you want a sling that is going to stay put and be comfortable to carry all day, the CaldwellA(R) HP Neo is the sling for you!
