Going to Peru... would this jacket hold up both in an Amazon style downpour and as a hard shell over a parka in the Andes? If not, any suggestions for something that could cover both?
Sure this would work great for those climates. Any of the lightweight waterproof breathable jackets will do fine. Just size it so that it will fit over whatever is the most insulation you plan on having on. (short of very high elevation in the andes 1 or 2 fleeces at most)
Just don't bring more of a water resistant wind breaker or an old lined ski-jacket and be surprised when you get hypothermic like a couple of friends of mine experienced.
