I have a Vortex Guide Binopack (AGC) and I have a Badlands Bino Basics harness. The Badlands harness doesn't offer any protection but it's lightweight and fits well. It works well for my 8x40s but not so much for my 12x50s. The Vortex is nice, lots of space, well protected etc. My only complaint is the straps don't stay as tight/snug as I feel they should.
