Scorpion's Velocity Men's Motorcycle Jacket, this is designed around a versatile waterproof textile and a removable fleece liner. When it's cold out the waterproof fleece lined liner keeps you warm and cozy, but when the thermometer points toward red just open the Velocity's two large pass through "Core Venting" torso vents to blow off a little steam. When it gets really hot, remove the liner entirely and take full advantage of the jacket's highly breathable mesh outer shell. The Velocity also features Sas-Tec C.E. certified armor at the elbows and shoulders. An optional Sas-Tec C.E. back protector is available as an accessory upgrade. Night riders will appreciate NightViz reflective strips for improved nighttime visibility. This is size LARGE
