I'm selling an item I purchased at a cycle shop but never used, so it's been sitting around. I used it only once and have kept it stored at home since then. To show its reliability, I've also attached an enlarged photo of the part that touches your rear, so please take a look. The size is S. I am 166cm tall and weigh 55kg, and it fit perfectly. (I think it would fit someone between 160cm and 170cm tall, and weighing between 50kg and 60kg.) These are thin bib tights with a brushed lining and Windstopper fabric. They are suitable for cold weather. You might feel cold in mid-winter depending on how you use them. I was told when I bought them that they are recommended for temperatures between 10°C and 15°C, so they would be good for autumn, late winter, and early spring.
