I bought these two years ago for skiing. I didn't get to go much, so I used the outerwear I had been using, so these are unused. The size is equivalent to a Japanese M and the construction is solid. I am 167cm tall with a 76cm waist, and the size is just right. They are a 31-32in size, so I think they will fit up to 81cm. They can be used for winter sports and outdoor sports! Outdoor pants with zippered pockets and an elastic waistband for a comfortable fit. - Brand: LITTLE DONKEY ANDY - Color: Blue - Features: Zippered pockets - Style: Outdoor pants - Design: Elastic waistband - Tags: Technical gear Thank you for looking.
