Choice of jacket top layer for mountains 5000-7000m

Guys, help me choose a top jacket for high-altitude mountaineering

Planned mountains:

Elbrus, Kazbek, Lenin Peak, Korzhenevskaya Peak, Ama Dablam,

I want to take one jacket for all occasions

Nikita Owrote:

one jacket for all occasions

Doesn't exist.

Lots of jackets that would fill that niche

I don’t even have this but the MH absolute zero. I’ve got the nilas which I’m in love with and can only imagine how amazing it’s big brother on steroids performs given that it’s warmer bigger n tougher outer shell.

have you done any mountaineering yet?

Obviously, only guides wear leather boots these days.

Western Mountaineering has great stuff too.

I have one and absolutely love it for belaying while ice climbing. It is very bulky but warmer than anything else I’ve seen. Very much a quality parka.

Yes, but also No.

It all depends on how you are layering underneath, if you have a thermal base layer a fleece and another insulated jacket on along with some puffy pants you will be fine. If you layer it with just a t-shirt and a light weight fleece it won't be warm enough.

It also depends on how fast you will be moving which will mainly be determined by your own fitness and how crowded the mountain is.

You’d likely need different clothing systems for several of the objectives in your list, but this coat is a good start.

The Positron itself is fine for this application. I've used it on warmer 6000m peaks without many layers underneath and been overly warm if anything and know people who have used it as their summit parka on Aconcagua and Pik Lenin. Dialing in the layering system underneath is where you'll make or break it though. A cold day on Ama Dablam vs a warm day on Elbrus are very different.
