Thanks Eilish for the suggestion to post a pic of the new jacket. (The photo isn't mine, it's from the Rocket sight but this is what it looks like). It's called a three in one, but actually has four layers; the outer hi-vis shell, the hi-vis mesh jacket, an inside rain shell plus the quilted liner.
The zipper configuration has completely changed from my current Rocket 3 in 1 jacket and the quilted layer is a new and welcome addition for riding in cooler temps. The jacket is a bit longer than my current 3 in 1 jacket but retains adjustable waist and arms and zipper to attach to my riding pants. There are zips on the cuffs and sides to open for comfort and convenience and a zipper vent in the back outside shell. I'm hoping that when I open the side zippers it will prevent the jacket from riding up when seated. I especially love that the mesh also has bright lime colour sections and that the zippers (for the various layers) are all color coordinated for the configurationlly challenged. (So what I really love is that it's a lot cleaner and bug free than my old jacket - for now)
I was talking with Ken tonight (he bought the same jacket at the show) and he mentioned he was disappointed there was no reflective aspect to the jacket. Ken, if you turn out all the lights ... the piping, between the lime and black (on the back) seems to be reflective, it's not a lot, but it's some. Perhaps the designers have decided if a rider has the sense to purchase a highly visible colour, they have the sense not to ride at night.
