I'm interested in what those who've used Paramo at altitude think of it, but one thing that occurs to me about your comment is that although Paramo gear is sold as waterproof, the outer is windproof and the lining is insulative - two properties which I'd have thought were very useful at altitude. But maybe, weight for weight and warmth for warmth, down would be better.
