I wear this when the wind just won't quit or possible front rolling through when riding near the shore. For air temp 50 deg. F and winds 15-20 I wear Craft Zero long sleeve base layer(wicking), short sleeve jersey (mid layer) and then Glaze jersey as outer layer. This combination allows me to stay dry and not get chilled. These conditions wind chill brings temp equivalent to upper 30's F. Going to wear this with a thermal in colder weather. Over all a great piece, made well and fit has ease to allow layers.
