These things work great. It is really the only way to carry binoculars. If you are using the single strap that comes with the binoculars you really need to buy these. Plus, Nikon makes great products. I have the nikon action 8x binoculars. The camo pattern is the same on the binoculars and the harness.
Pros: keeps your binoculars where you want them, close to your body
Cons: none really
