Super light and unobtrusive and seems durable. Doesn't make me hot wearing it like I think most bino harnesses would. If I adjust it so that binos are high on my chest, I have to pull against the shock cord to get them up to my eyes. At the end of a long day, my eyes hurt from pushing lens cups into them and my arm was tired from pushing. So I loosened the cord them to give myself more slack. The top of the binos are now about level with the bottom of my sternum. This results in a little more bino swing/bounce, but it's tolerable. I was worried about abrasions from the cord but that was not really an issue. Minor aggravation under my armpit from the cord pulling and moving under my shoulder straps. I think this will almost go away with the looser mount. Haven't tried the side mount for a day yet because I don't think the binos are as easy to grab there.
