This is the perfect hat all seasons, in spring and fall it is just right, light and warm, in winter it is a nice thin layer under a hood or helmet. In the summer it is small enough to fit into a pocket on camping trips to wear in the evenings or by the fire. The mix of merino wool and silk is light, soft and gives protection without heat buildup. Also available in children's sizes.
*Measure your head around the brow and you'll have the size you need!
