After using a Vortex GlassPak for years, I decided I needed somthing with a few more pockets and room for my rangefinder without having to add a separate pouch. There are a number of top tier bino harness manufacturers, but ultimately I landed on the AGC Hybrid with M.A.X. pocket. Construction is excellent, providing a ton of extra storage without being overly heavy. I really like the tether system--it doesn't get tangled up but is quick and easy to detach if needed. I do wish they had done a buckle-less attachment at the top of the pack, so I can let the pack sit a little higher on my chest, but I plan to remedy that with something like the Marsupial Gear Buckle Delete Kit. Other than that, I'm 100% satisfied with my purchase and highly recommend AGC if you're looking for a new bino harness!
