The RST Pro Series Ventilator III Jacket and Jean is the ultimate RST sport/touring textile. The Ventilator III is the most versatile textile jacket and jean combination RST produce. The Ventilator III has a BALLISTIC/MAXTEX/K492 MESH outer and a removable HUMAX-Z waterproof/breathable membrane combined with a separate removable 75g quilted lining, this provides the perfect combination for both summer and winter riding. Wear the fully armoured outer on its own if the heat is on, or add the inner HUMAX-Z lining to create a windproof/waterproof pairing if the weather turns. Or add the quilted lining to provide all the warmth an all year jacket and jean combination require. Finally wear all three layers together when the weather really turns against you.
