I bought this from a fellow Lounger about 3 years ago. It has been a great jacket for casual wear but now it's time to pass it on. The Horsehide is probably around 4.5 oz and is the Aero Tumbled CXL Horsehide. This jacket shows a lot of grain so if it's patina you want then this jacket meets the requirements. The jacket is heavy weighing in around 8 lbs. The sleeves are slightly narrower than the standard because it was manufactured without the wool inserts at the bottom of the sleeves which I really like. It is not tight in the armpits just a very slight adjustment. The lining is the heavy duty Cotton that Aero commonly uses. The measurements are as follows: Armpit to armpit: 24.5" Bottom Waist: 21" Shoulder to sleeve: 24.5" Shoulder to shoulder: 19.5" Back of collar to Bottom of jacket: 26" See Photos with tape for more info. Note: This jacket is for a person of average height. My weight and height is 5' 9" and 190lbs. in photo. Asking $700.00 ship free and insured in the Continental U.S. only. International shipping is possible with additional cost but be aware it will only ship as fully insured so this could have a major cost for VAT Tax.
