I purchased this from Amazon and used it about twice. There are some slight stains, but I think it's relatively clean. It's Asian size M (European size S). It's designed to be a bit roomy so you can wear thicker clothes underneath. From the product description: * Windbreaker cycling jacket with both waterproof and breathable features, with detachable sleeves. * Uses waterproof, lightweight fabric (water pressure resistance 5000mm & breathability 3000g/m2/24 hr). * Detailed features such as a hem drawcord and a mesh panel on the back. * The jacket can be packed into the back pocket. * This jacket is great for cycling, running, and everyday use.
