From Glen in Pensacola:
Simply the best
The S4 Gear Lockdown Binocular Harness has a few features that make it stand head and shoulders above all other harness systems.
First off, is fit and comfort. The wide back panel spreads the load evenly across your back and shoulders making the binocular load all but disappear. I use Theron 8x42 apochromatic triplets and they're heavier than normal with the extra glass but when in the S4 I forget they're there. There is no strap dig, no undue pressure...it's just comfortable as can be.
Secondly, the binoculars are protected very well in the cover. Most harnesses simply leave the binoculars hanging in the open, unprotected. Oh sure, you could re-cover the lenses every time...how convenient is that?
With almost every other harness system out there you get that pain-in-the-arse strap tightening as you bring the optics to eye. Yeah, I know, they tout that as a "feature." I'm not quite that stupid. The S4 uses adjustable tension bungies attached to the shoulder sections. You simply flip the cover off, pull the binos down and out, and bring them to eye. The bungies go slack at that point. No pulling under your armpits, no tight straps.
Side benefits would be great build quality and a nice price point. Overall a great product that goes above and beyond what it is designed to do.
