I bought this last year and used it for snowboarding. The size is XL, and I'm 178cm tall and weigh 60kg. I wore it a bit loose. Here's the product description: 【Half-zips are becoming a trend, and are now a staple! You can't go without one this year either!】→Murasaki Sports Exclusive •Detail Moderately thick material.
