Hi, I am a proud owner of an Aero Sheene (= Aero Cafe Racer with Collar) in Size 42 which I ordered from Aero Leathers in November 2015. Unfortunately, I have gained a few pounds (both muscle and fat) since I bought the jacket (I am 180cm and 84kg now). Now I feel that the jacket restricts the movements of my shoulders too much. The jacket especially feels too tight around my lats (upper back) when I (try to) antevert my arms. (I did a lot of pullups since I bought the jacket). Unfortunately, I bought the jacket without a biswing back which probably was a mistake. I think the shoulder width is probably still o.k. Now, I rarely wear the jacket because it feels to tight with a sweater/pullover underneath. And that's not what the jacket deserves ;-) I am now thinking about two options: 1) Order a Sheene with biswing back in Size 42 (or try to find a used one on Ebay). 2) Order a Sheene with biswing back and ask for a special size 43. Specifications of my jacket: - Size: 42" - Leather: CXFQHH - Lining: Brown Cotton Drill - Storm Cuffs: No - Sleeve Length (according to Aero Production Sheet): 25.75" - Body Length (according to Aero Production Sheet): 27.25" What do you recommend? Greetings from Germany, Philipp PS: In the images, I am wearing a sweater/pullover underneath the jacket. Sorry for the bad quality of the photos.
