I've have a couple of Triumph nylon jackets and they are very nice quality. I believe Triumph hit a home run on their apparel line as they have on their bikes. I've tried on several of their leather jackets and to me they are of equally fine quality like the Harley line of leathers.
However, line Harley, they are very expensive. There are a number of them I'd like to have but I just won't pay that much for leathers. To me the style and quality are superb; just too expensive.
