I've tried about 6-8 different chest rigs over the past 5 seasons, starting with a harness and now with the AGC Bino Pack.
There is NO WAY I would trade it for anything else on the market. No chance.
The protection it offers, capacity it has available and comfort the new straps provide is nearly impossible to beat.
As others have said, it's not just about keeping your binos close by...it's about keeping ANYTHING important close by.
Mine easily holds, 10x42 Fusion 1600s, Kestrel
4000, my cell phone, Lens pen, folding knife, skinning knife, 6 predator calls, tags, ID, windicator powder and a Sagen Saw...with the front pouch still empty for more.
My partner is working on an HD video review soon...but we're not going to post it here, as it's probably going to look too much like an advertisement.
