Well, just to finish this thread off, I finally ended up with an Outdoor Research Chaos jacket.
I tried the Juggernaut, but the hood was really tight over a helmet, pulling the jacket up off my shoulders.
The Chaos is actually designed as a belay jacket, ie to fit over your hard shell, so I got a medium (my normal size) The hood fits easily over my Petzl Ecrin Roc, but will also snug down over my bare head, thanks to the three way adjustment.
Gore Windstopper outer, with Primaloft insulation. It weighs in at 676g (about24oz) on my scales, so around the middle of what I was looking at.
Includes an inside mesh and zip pocket, and a velcro hang tab? that I still can't work out the need for. Sleeves are velcro adjustment.
It retails at $240, but the guys at Seattle's OR store gave me a smoking deal, which put it right on par with the Juggernaut. The clincher was that some of the Mt Rainier mountaineering schools are offering it as a rental. It must be pretty durable!!!
Definitely worth checking out for the PNW guys.
