Hello friends, Was looking over my Aero J106 today which I purchased a bit over 2 years ago from a member here. It was in brand-new condition when I bought it, and I have worn it quite a bit in the past 2 years. To my dismay, I found it already has several dime to nickle size holes in the bottom seam area of the lining. This is the Wool Tartan, made by Lochcarron of Scotland. To be fair, I do not think the material itself is "weak" however it really is in a high wear point at the bottom of the jacket. Being a motorcycle style, this jacket has a thick inner kidney panel that keeps at least some of the lower seam from extensive wear. Please see the photos below for details: Since I did not buy the jacket new, I really have no recourse with Aero directly. I guess for the amount these jackets go for, I might expect a little longer period of wear before having to face a lining replacement. That said, I believe all future jackets of this type I order will be with the heavy cotton drill lining. That is the sleeve lining in this jacket, and it really does not show any wear, even at the sleeve cuff ends. I do believe Aero offers a 3" or 2" Corduroy lower seam lining option, and given what I have experienced, may be a good idea if a Tartan lining is specified.
