Abstract: An outerwear garment is provided which comprises a sleeveless vest having a kidney extension flap at its lower back portion. The kidney extension flap has an interior portion which defines a pouch. A jacket having sleeves is connected to the lower portion of the vest adjacent the pouch. The jacket may be inserted into the pouch when the vest is worn in a sleeveless mode without the jacket, or the jacket may be withdrawn from the pouch and the jacket's sleeves may be inserted through side openings defined by the vest.
