Pace Marino Wool Cycling Cap is great on and off the road.  First of all Marino wool is natural, sustainable, renewable and biodegradable.  It's great off the road because it will keep you warm while looking cool.  The Marino wool is great on the road because, like we say, it's warm, fits under your helmet, moisture is absorbed and released, resists order build up, can be washed in cold or warm water, and it just feels good.
