Kuiu bino harness is only experience that I have but I love it!! The rain cover has been my best friend in western washingtons moody weather. I actually love the little pouches on the side I'll put calls in them or a couple extra rounds, I would put two 00 buckshots in the right side pouch, just in case something larger interfered with a turkey hunt, made me feel comfy, since my sidearm is only a 9mm(I know,I'm working on it). I actually really like using the elastic piece that allows you to remove the pouch, binos are fully exposed but they feel so secure still!! I am 5'10, 155/160 pounds, I believe I have the smallest size and they fit awesome!! I'm still tempted to trim the webbing off cause they hang all off my skinny frame.
