The vest is an SDS RACK(aka ranger rack) in 3 color. Great piece of kit. If you guys really want a lightweight kit, a lot of manufacturers are coming out with 'ultralite' kit. Tactical Taylor, blue force gear, first spear just to name a few. I can post some links when I get to my laptop.
Looks good. I would fold the bib down and move the radio to the shoulder strap. But that's just personal preference for me. Love the rack though. Looks good man.
My vote for the ultimate light weight vest is the ten speed line for Blue Force Gear. Four pouches that can hold just about whatever you want with no slipping and molle on the sides if you need it. It fits to the body flat and it's priced awesome for some legitimate kit.
