Is that the cotton carrier as well?
Yes. That's the Cotton Carrier Vest. I bought the Cotton Carrier vest and holster in December 2009. It's a good system, but having had a camera drop to the floor when wearing the holster at the waist I have become very wary of it. There is no problem when wearing the holster attached to the vest.
The Cotton Carrier system is better when you want your gear immobilised, such as when climbing over obstacles or negotiating difficult terrain, either on foot or bike, but it does look pretty nerdy, at least when worn without the concealment of a jacket (mind you, a DR-1 or DR-2 will barely look any more "normal"). The problem is that either you use tethers (none supplied at the time I bought mine, and hence the accident) or you have a camera that is attached to nothing at times and requires precise re-fitment into the carrier to ensure it is secure before letting go. The problem I had was that the camera insert simply unscrewed itself as I walked along. I had ignored the recommendation to use Loctite, so I guess it's my fault, but I do think there is a design weakness there, which is maybe why they added tethers to the system later on. TBH I really think they should have sent tethers out to all existing customers, FOC, but they didn't.
With the DR-2 I feel slightly less like I'm fitted out for a tour in Afghanistan and I feel my gear is at far less risk of meeting an untimely end. I also think it is a little quicker (and safer) to swap cameras with the DR-2. The downside with swinging straps is that they swing, so if you are highly active they might cause a lot of inconvenience.
As a consequence I keep both systems, although apart from that photo above, taken purely for illustrative purposes, I have not used the Cotton Carrier once since getting the DR-2.
