These are my wet weather, cold weather, raining, muddy, everything mountain biking pants. The material is tough, and the construction is excellent. I have a 1.5 year old, and a 2 old month pair, just so I always have a dry set for the next day. I need weather resistance and breathability and these provide that perfectly. Both pairs have been involved in various "I am no longer on my bike" incedents and have come out without damage, they are really adding an excellent layer of abrasion protection for my legs. Fit for me is trim through the butt and thighs, with enough space at the knee to run some light pads underneath, the calf is loose enough to not look like tights and does not interfere with the drivetrain at all. I am 6' 1" and 165 lbs. These are excellent do anything outdoor adventure pants.
