The stuff works. Not sure of the science behind it but I wore it snowshoeing today and up top I had a pretty basic Burton dry-ride polo and gore-tex shell that got pretty sweated up. For bottoms I had a pair of the Homeschool lounger pants and some North Face cargos and they stayed bone dry and warm.
But I don't get what it does. It's supposed to be used as a hyper efficient insulation layer? Which piece was cocona?
