I bought these pants specifically for mountain biking in cooler temps, as an alternative to the over-branded motocross inspired alternative. In short, super stoked. The understated look makes a seamless transition into après possible without changing clothes. I was truly impressed by the comfort on the bike. My first ride in these was The Whole Enchilada in Moab -- 30 degrees at 11,000 ft and 75 degrees at 3,000 ft -- I was pumped on how comfortable these were at each end of the ride. To my surprise, I didn't feel like I was overheating in these when the temps went up.
