These casual pants are labeled as mountain biking pants. I'm a mountain biker and have no idea why they are using this label, maybe because they are 'water-resistant'. I haven't tested that yet, and I don't think I'll ever wear these while mountain biking, but as far as casual pants, they should be very good. I'm a 37-38 waist and these pants in XXL are perfect. They have a stretch waist band and a drawstring for lots of adjustability. I also ordered gray and received the dark gray instead, which is actually black, but not a big deal. There is some contrasting stitching in several places and what they call a '3D' knee is actually just a bigger than normal knee area. There are two side zipped pockets and one zipped back pocket, as well as zippers at the bottom of the legs to allow for boots. I'm a 34" inseam - these in XXL are a bit long, but also not a big deal. This will be a good addition to the casual pants wardrobe!
