My go to primary layer
"Light, compact, versatile layer. Used this layer hiking in the arid heat of Zion, shore fishing in the tropics of Hawaii, and as a primary layer on my enduro motorcycle. Pros: surprisingly comfortable sun protection in hot, humid and arid environments, decent insulation when worn with a shell, great stretch fit, 4 season versatility. Cons: Not quick drying, but the wool keeps you from getting too chilled when damp."
