I've discovered the Scottevest company about 5 years ago. And is a happy owner of several products from them. In the last years their products quality dropped noticeably (cheap zippers, bad stitching) as my friends has reported. Just checked their web site - looks like they have far less options than before. That's sad - the EDC idea was very well implemented by their designers.
I'm still wearing their Tactical 4.0 system (Fleece vest + rain jacket, all with detachable sleeves) - very versatile and high performance construction. The fleece vest part of it was my primary EDC items carrier - it weights around 6 pounds but that's almost unnoticeable. Unfortunately my new job has a classic office dress code, so I'm only wearing it off duty now.
The roomy jacket part serves as a part of my grab and run BOB system. It has very reliable inner harness system which allows to pack a lot of stuff. Once in the airport I've managed to empty my luggage for more than 15 pounds, moving my stuff into the jacket pockets, in order to avoid the overweight fees
And you are right it's not very durable in the field (though quite comfortable) - I had to get a replacement for the inner fleece west after about 2 years.
