I purchased this item to use for birdwatching. I'm not a small guy (257 lbs.) and this harness fits fine without being uncomfortable. Holds the binoculars close to my chest, no bouncing around.
Perfect support for my binoculars. It gets the weight off of my neck. The included rings allowed for an easy attachment to the binoculars. You can't beat the price for this one.
Since receiving this harness in early February 2012, I've used it on three hikes. It holds the binoculars firmly against my chest with no bouncing as I hiked. I can now easily lift the binoculars to my eyes whenever I want to. It is easy to put on, comfortable over a shirt and under the backpack. I've used my binoculars more on these three hikes than ever before and it is because this harness keeps them at the ready while freeing my hands for more important uses!
