Yak wool has similar properties to other animal fibres, including breathability and static-resistance.  In woollen garments air pockets are created between the figres that reduce the rate of heat transfer.  This property combined with Lanolin (a hydrophobic grease present in wool fibers) allows the wool to keep you warm.
