The Caldwell Max Grip Sling's ergonomic shape is designed to spread the weight of the firearm for a comfortable carry. The over molded design of the material grips your shoulder so the firearm stays put no matter how strenuous your hike is. The sling is completely sealed to be scent free and not take in any moisture as you hunt through all of the elements. If you want a sling that is going to stay put and be comfortable to carry all day, the Caldwell Max Grip is the sling for you!
