Try on Paramo analogy insulation systems, they work superb. I am guiding in Colombia where it rains over 3000mm yearly and thats a lot, and when it comes in terms of breathability Paramo analogy is the the choice.
Yes it is a bit heavy on the counter part and is not fashionable, but who wants to look like paris hilton when climbing in rough mountains, functionality comes first in my opinion.
Cheers!
