Hey fellers, /k/unt here.

I'm going trekking into the Peruvian Andes in 3 weeks and putting together some kit.

Anyone recommend the PCU system of clothing for such a trek? It was developed for special forces in the dry, high and cold mountains of Afghanistan.

I plan on getting the hardshell, the baselayer and a fleece.

Also open to other gear, heard good things about the Russian Gorka mountaineering suit.
