Moutain Hardware Fleece Beanie
Not a whole lot to say here. Warm, cozy and weighing in at a whopping 0.8 oz. I live in this hat. Either early in the morning on a trail keeping my warm, late at night in camp while cooking and hanging out, or tucked up in my sleeping back for extra warmth.
Hhhmmm…. maybe it’s time I washed the thing. 
Available from REI for $15.
