These are much tighter and shorter than breeches in my size usually are. I struggle to bend my knees fully because of how thick the fabric is around them (bulky behind the knee). The full seat has no flexibility. I heard the seams tear a bit the first time I rode. The ankle portion is not reinforced well at all - under no unusual stress they pulled in several areas, leading to runs and a hole.
The pockets aren't too bulky, and gapping at the waist isn't too bad. These haven't stained yet, they're easy to brush clean. (I got them in gray.) I just wish the material (especially at the knee and hips) was more stretchy and less bulky.
