I purchased this at a store a few years ago. I've worn it about 10 times. I liked the color when I bought it, but I haven't had the chance to wear it as much as I thought, so I'm selling it to someone. The official size chart is included in the 7th image, please refer to it. Gender: Men's Size: 1 (S) Features: Water-repellent, Windproof, Thermal/Cold Protection
