*Note*: The measurement you provide will be the actual jacket front length.     On 3/4 Length jackets if the front length does not extend a minimum of 2 ½” below the waist belt line, it should Always be zipped to the pant. When the front jacket length is lower than 2 ½” below the waist belt line it is not mandatory to zip to the pant. Short jackets can ride up the torso while riding or in a tumble.
