These are winter cycling pants. They're quite warm, and the material doesn't restrict movement. The seat pad is also well-made, and they don't feel cheap. There are convenient small pockets on both sides of the thighs. Regarding sizing, they are Asia size M. I'm 170cm tall and weigh 58kg, and the size fits perfectly. The last photo shows my own tights with a smartphone in the pocket. They're easy to move in and are comfortably warm. These are my favorite and recommended winter long tights. Thank you.
