Is the wool waterproof?mmusc 2y agoIf it's damp wool is one of the best things you can wearFredPret 2y agoPerhaps, but unless there's a way of processing wool I've never seen, it also lets lots of wind through and doesn't insulate like a bit of dry duck down (nothing does). And you have to keep the down dry.
