In reply to Carol Goodall: Well, I took my aspira set when I went to Kyrgyzstan, Tien Shan, a little over 5000m and it performed flawlessly. Disclaimer, all the paramo gear I had was sponsored for the expedition but I'd never used it or really considered it even before I got it and was pleasantly surprised. In fact, the paramo gear strikes me as the perfect shell layer for expeditions and winter. You won't get rained on and the shell is only for protection from the elements otherwise. I am not a fan of the stuff in the wet though. What it does do is breathe far better than any gore tex shell which I found fantastic for when it isn't awful weather meaning you don't have to faff with taking off and putting on layers all the time.
I climbed in a base layer and my aspira smock, when the sun came up and it started getting warm I rolled up the sleeves of the smock and undid the zips. When night came I rolled down the sleeves and zipped up. When we hit two in the morning I put on a belay jacket. Had I been in a traditional gore tex outfit I would have had to take it off after about seven in the morning the first day if I wasn't sweating like a pig before then and put it back in the evening. I would probably have had to put on a belay jacket every time I belayed as it would have been too cold for a softshell alone while being stationary but too warm for a gore tex jacket.
In short, I think it is the perfect clothing set up if you aren't expecting to get rained on. I know lots of people prefer it in the rain but I'm not one of them. I used aspira smock and salopettes, my friend used a velez smock with one of their velvety looking fleeces and aspira salopettes and his seemed like a slightly more comfortable solution actually.
