The only M/C jacket I ever owned was a heavy leather jacket which I didn't like. It must have weighed 20 lbs and I felt like I was donning lead armor when I put it on. So I sold it. A friend of mine has a mesh jacket that I tried on yesterday and I was thinking of buying one. His is a Fieldsheer with a removable liner. It was 90 degrees yesterday and he said it was comfortable as long as we were rolling. Do any of you have a recommendation or preference ? I would like a light weight jacket that would be comfortable for summer morning temps in the 60's up to 90 degrees. Over 90 and I don't need to be riding. It's just plain too hot.
