Our "Best Value" in G-1 Flight Jackets. The classic USN G-1 style has been the garment of choice for Navy pilots ever since WWII and is still in use today. The Legendary Hellcat G-1 Flight Jacket is designed in heavier 3.0 oz Goatgrain Cowhide leather for daily use and abuse (current Navy Contract utilizes goatgrain cowhide). Unlike others, our Exclusive Legendary design offers civilian-friendly hidden twin side entry pockets for additional cargo.
