The above was written by Mercari AI. These are Skins A400, size S. They fit perfectly when I was about 168cm tall and weighed 58kg. Recently, I've started using Finetrack Sky Trail pants and haven't worn these much, so they've been stored in my closet. They show signs of use, but I think they're still perfectly usable. They're quite expensive to buy new. How about giving them a try? Personally, I found them more effective than Wacoal CW-X and used them accordingly.
