I have a Feathered Friends Volant jacket for sittin' still high up. I have a softshell jacket and lighter layers for moving around in.
The course I'm taking is a multi - trip one with Bushwhackers (a la Mountaineers, but smaller class size), and I don't think they have an 'official' recommended list. I've scoped out lists from Mountaineers, and Alpine Ascents International's recommended lists for their trips. AAI's list could read "bring the most bling blingin' equipment that money can buy to our course".
I am interested in purchasing reasonably versatile equipment, and the Patagonia Grade VI jacket isn't being made anymore, but a comparably priced jacket is the Patagonia Jetstream; it is marketed as a jacket geared towards alpine climbing and backcountry skiing, and looks like it would complement the softshell system I have working nicely.
The course does an easy snow camping overnighter, then a four day trip on Baker in early/mid June. The club will be doing a trip up Emmons Glacier on Rainier in late July that I am planning on attending, as well.
