GUARANTEED DELIVERY BEFORE CHRISTMASRESTOCK DUE DECEMBER 9thBased upon the original WW2 1940 RAF "Battle of Britain" Sheepskin Aviator Jacket designed by American aviator Leslie Irvin, our own unique take on a British classic is made from 100% British Sheepskin, and includes a double-panel back as opposed to the traditional four-panel, demanding only the best and purest Sheep hides (due to their size), and resulting in a much cleaner and premium quality jacket. Additional improvements on the traditional design include re-inforced belt loops and box stitched belt-ends, with a double-thickness belt, collar strap and zip pulls, all resulting in a far more durable and longer-lasting jacket. All zips are the best that we could possibly buy, and the jacket has been hand-finished with solid brass fittings throughout (including a unique brass belt close), with Goldtop motif rivets adding further definition to all zip pulls.Sizing is true-to-size and will appear "fitted" if you are planning on wearing this jacket with a t-shirt or thin jumper, however, we do advise going for one size larger than what you would normally wear if you are planning to wear this with a thicker jumper or alongside one of 100% Merino Wool Submariner Sweaters!See a review of this jacket on YouTube here: https://www.youtube.com/watch?v=j0oGnhXSvRM Please email info@goldtop.co.uk to be informed as soon as they are restocked
