In summer I wear it with a T shirt. In winter with a Gerbing. I've stayed warm in winter, cool, or at least as cool as anything else I've had, in Eastern and Western heat, and most of all I've stayed drier than anything else I've ever owned. On an 800 mile day at 40* and an all day rain I like that a whole lot. I have about 40k on the suit. Oh yea, I broke off the main zipper pull, a dealer replaced it for free in about 5 minutes. I had put a split ring on it which a salesman noticed and offered to repair it.
I had a minor get off and abraded the left knee a bit, didn't feel a thing at the scene or later. Fits great and the flexibility feels like I'm wearing a mesh suit. At the same time it feels like and is very well armored. Price? Much less than I spend on tires in a year.The jacket zipps together with the pants, is shorter in front and longer in the back and doesn't bunch up in front like a rally length does. By the way, it does all this stuff with no liners. No stopping when it turns very, very gray.
