I bought a neoprene sling for my rifle to test it out, it only lasted one day in the field before I took it off and went back to my trusty leather sling. I didn't like the feel (how it stretched) on my shoulder, I kept thinking the gun was going to slip off (even though it did grip better than my leather sling). I like the feel of the gun tight against my back when I'm walking, and in my opinion, the neoprene didn't offer that (at least in the sling that I was trying).
