I've actually wanted this harness for quite a while. What kept me from ordering was the price. The system is expensive in itself, but I also wanted to get the quickcase and two utility pouches to go with it. Came to about $250. Ouch. Could have bought a pack for that... Anyway, I obviously chose to purchase the product despite that, so I'll give you a review. It's actually pretty solid. I'm a bigger guy, and even with my gut it fits me, and it doesn't move around at all, which is important to me. It's also very lightweight. I could almost forget I'm wearing it. I also wanted to get use of this when I'm not using binos, so I use it when I'm trail walking. The large will hold a GI canteen or two 16oz water bottles in the main pouch. The magnetic closure is solid and can be opened with one hand, but is honestly easier when you use two. The closure also stays down when opened, which is nice. I have a ton of Eberlestock gear and this is one more piece that I am impressed with.
