The Concurve jacket preforms in all weather conditions, but seemingly best in the worst weather condition's. The hood is a game changer during cold windy, or mixed precip days. It fully protects your neck area front to back and helps hold your body heat in. The jacket is a very lightweight final layer that offers excellent wind and water protection. It has kept me comfortable in my daily commutes with a base layer 1 down to -11 degrees with a windchill of -24 degrees thus far.
