These are slim-fit knee pants from when entwa was kazenosumika. They are made of a tweed-like material, making them warm pants for autumn and winter. I purchased them from the official website around 2020. They have a basic design, but the area around the knees flares out slightly, and they taper nicely towards the hem, making them stylish just by wearing them. I've worn them about 10 times and have been storing them folded.
