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 the size, they are Asia size M. I am 170cm tall and weigh 58kg, and the size fits perfectly. The last photo shows my own tights with a smartphone in the pocket. They are easy to move in and are comfortably warm. These are my favorite and recommended winter long tights. Thank you.
