Putting a radio, or anything else that is hard and a little bulky, just to the right of my left nipple isn't a good idea, IMO. That's right where the shoulder harness goes, and just about over my sternum. Maybe I'm not as broad as Genghis, but I emphatically do not want a gun pocket, nor any other pocket, there. I haven't worn one of those jackets, but they look remarkably like the standard ski jacket from many of the online outdoor retailers in the US. I have a leather flying jacket, and I like it most of the time, but the stretch stuff around the bottom isn't the best idea. It rides up and leaves your kidneys exposed during preflight when you're climbing around. The Mk3 and similar are an improvement there. I have one sort of like it, but in nicer colors, with a zip-in liner, and it works pretty well, but I admit I wear my leather jacket most of the time. The sleeve pocket with pen slots is one thing I miss about all my current jackets. Do not leave that off.
