Comfortable
First time user of the ISM saddle for commuting, and coming from a cushy foam saddle this felt a bit hard initially. But after a couple of weeks in the right setup, it has conformed to me and is very comfortable. The right setup is very important, as from my experience with riding with the wrong setup for a week (saddle too far forward) made it very painful near the inner thigh/hip joint after a few kms. In the right setup, I don't think I will bother searching for another saddle again.
Pros: Comfortable, Good Fit, High Quality
