Double vented by the way. It is a solid navy 4 season wool. Appears to have some crumbs or something like near the back of the collar, but it will come out with water and a finger. This thing should make it through the night (but maybe not). It certainly won't make it long tomorrow though. One of us needs to get this. It is in the "prestigious store, 50% off" rack. It wasn't with the 44R's when I was there. It was just on the short side of the rack.
