I have to say that im surprised with this product. I bought it to spend 20 days of February in the UK, and it worked wonderful. A t shirt, a sweater, a pair of gloves and this jacket is everything you need. If you close the jacket to the top button you wont need a scarf and If you use the hood you wont need a winter cap. Is that simple. One internal pocket, and two external ones. Used every day and I didnt get cold once. And yes, you can use it in the rain. I bought one size extra just in case and fitted nicely. Im 6.2 with long arms and I weight 200 pounds and XL fitted perfectly. You wont regret it
