mtn momwrote a review of Mountain Hardwear Sub Zero Parka - Women's on April 10, 2008
Yes, I do feel like a Michelin man, but toasty warm. I compared this to two other synthetic jackets (REI and Marmot) and also to the sub zero jacket and TNF Nuptse. It has length, really light weight, and heated me up immediately. It could use another inside pocket (for stowing batteries and other stuff you need to keep warm at cold high elevations), but it should work well for winter mountaineering.
