i think insulator means it keeps you warm? while ventilator means keep you cool in the summer? i wore it in the ozark endurance run just few days back and the evening temperature was about 40s low to 30s high and throughout, i never feel cold in my lower body. now, i'm thinking if i should invest one in the upper body.
