it fits my 10x42 zeiss binos well. It's mostly comfortable. The buckles and pouch seem to be constructed well. I like the molle webbing on the back and the pouches on the front and back of the bino compartment. I give it 4 stars for a few reasons... i feel like no matter how I adjust the straps, they don't fit me as snug as I would like them to. The top of the pouch hangs away from my body and I don't really like it, although I've gotten used to it. Also, the synthetic mesh stuff that is sandwiched in the straps has threads that poke through the sides of the straps. It seems petty, but those little threads poke out just enough and are stiff enough that after wearing this harness for a full day, they created sores on my neck from rubbing on it.
