I didn't have too many miles on this saddle before starting the tour around Lake Michigan, so I wasn't positive what to expect - the first night, my ass hurt, and I was worried. About 400 miles in, the saddle had noticeably softened and started breaking in. Soon after that, I had reached the point where I had no noticeable discomfort, even after a 130 mile day.
I attribute a great portion of my comfort and ability to stay fresh throughout the trip to this saddle - I'm a big fan, and am completely satisfied with the investment. Not to mention very happy with how cool it looks on a blue Surly LHT frame.
