High altitude women's/Unisex parka Recomendations

I am having a hard time finding a high altitude women's or unisex parka under $500. Does anyone have any suggestions? Looking to buy something for winter mountaineering. All of the mountaineering "Parkas" I am finding online seem to be glorified down winter coats not   Alpine climbing Parkas (though their names suggest otherwise). 

What Parkas do you recommend?!?!?

Also, I would love it if someone can point me in the direction of product reviews (FOR WOMANs Alpine climbing gear, if it exists). 

How cold and what use, does it need to withstand sharp rocks or just snow and ice, would you wear it moving or sitting still?

Rab Neutrino Endurance or Positron.

I am very happy with my Mountain Equipment (the British brand) Dewline for jacket. I think their jackets have a good price/quality ratio. The Dewline is pretty much a lightweight down jacket (lightweight fabric, style) but has a lot wider baffles and some pretty serious down insulation. It's kept me warm down to minus 15/20 C and for me the women's fit is very comfortable. It's not really an issue with how I use it but a trade-off for the great warmth/weight ratio is durability. You're pretty much wearing a sleeping bag. For me it's warm enough but that's for ski touring/winter climbing in the Alps. You could check out their Lightline for a more substantial high altitude/expedition jacket.

I agree that it really very much depends on what you will do with it :/ 

I second recommendation for Rab and Mountain Equpiment!  Both UK companies have a fairly robust technical offering in women's specific models.  I have two down jackets from Rab, a box baffle parka (Alaska or winter camping) and big puffy (Infinity Endurance? that I wear for alpine climbing/ice climbing/mountaineering, etc.). 

Are you actually planning on using this parka at high altitude, or just want something expeditionary warm for ice?  If so, I don't recommend shopping on a specific budget.  If it were me, and I was spending "X"  amount on an expedition to a 6K-8K meter peak, then I'd want something that first and foremost fits the best, and secondly, meets the temperature requirements for the conditions I plan to encounter.

I'd give Feathered Friends a look, followed by Rab's Expedition line.  Most, if not all, high altitude specific down parkas are probably going to be more than $500, unfortunately.  Think of it like this - Do you want to skimp on something that not only may save your life in the event of an emergency, or shop on a budget & buy something inadequate for the conditions?
