1 Merino is one of the softest types of wool available, because of finer fibers and smaller scales.  Merino has an excellent warmth-to-weight ratio compared to other wools, in part because the smaller fibers have microscopic cortices of dead air, trapping body heat similarly to the way a sleeping bag warms its occupant.
