These are Japanese-made cold-weather pants. The size is M. We purchased several pairs as a family during the Great East Japan Earthquake. I believe one pair cost over 5,000 yen. They have been stored for a long time without being used, so they are unused stored items. As they are made in Japan, they are carefully crafted. The zipper is YKK, so it is very smooth. There are holes next to the waist button, allowing you to thread a string through. Although they are size M, they are made with a relaxed fit, so you can wear thermal underwear like Heattech underneath. While they may not be the most stylish, they are very useful for keeping warm. Would anyone looking for these be interested? Shipping will cost 750 yen, so we would appreciate your understanding of the price. Thank you very much.
