Here is my Royal Air Forces Association Authenticated Sheepskin jacket in L. It is the real deal as very few others carry the RAF Asso authentication. It is made to the original RAF 'Irvin' pattern in full English sheepskin - made in England (Glastonbury) which the RAF Asso insisted upon and available only through Danbury Mint. It has 2 front pockets which not all such jackets have.
I've had this for about 7 years but it has been little used and well looked after. I'm having a clear out as I'm getting on a bit and can't see myself wearing it much. It is just perfect to wear when driving an open classic car in our climate. It is in top condition, no marks or repairs and all zips work as new. It measures 24in from pit to pit when laid flat but you have to allow for the thick inner sheepskin. I'm a 41in chest and I have a little room so it would be ideal for someone 41-43in chest. You won't find better. Moreover, it is priced to sell.
