I was really nervous about the fit. I have had numerous jackets by other makers and I always seem to be between sizes or some aspect of the jacket wouldn’t fit. ie sleeve, body, shoulder, length. Most companies don’t let you make changes and if you do it messes up the whole pattern. You can’t just size up or down and expect it to work everywhere. This is one reason that made me really look at Langlitz. I knew the quality would be exceptional and it is. I simply followed the instructions online. I had my wife measure me. Langlitz did the rest. Medium fit and Medium cowhide is just perfect. It is going to take some time to break this thing in for sure. I got the standard two pocket Columbia without belt loops and very glad I did. I was also impressed at the feel of the lining. I have never felt anything like that. Not your typical thin silk type liner. Sleeves are a little long, but should crease and shorten up about an inch and be spot on. shoulder, pit to pit, back, front length is all great. Could not be an easier process. And to top it all jacket took just a couple weeks to make. I got a matching wallet and belt. I went with their recommendation on belt size and it’s spot on. Best part too if something isn’t right they will take care of you. I have heard first hand accounts of exceptional service. I think if you are on the fence just go for it!. the price tag is really good I think for what you get. One could easily spend the same and get a much inferior stock type product that is mass produced and using inferior leather and hardware.
