This is a heavy, winter jacket for very cold climates, and, like the name of the brand suggests, it is an any kind of weather, proof jacket; that means that it’s impervious to hail, snow, rain or wind. It has a fleece like lining that is like a fleece vest within the main outer jacket, and although this vest is made of Polyester, it is just as warm as real fleece. It even feels like fleece. It’s an awesome utility jacket; when you open the jacket fully up, there are multiple pockets on the fleece like inner lining, even one for an iPod, which kind of dates this jacket and probably makes it Vintage. The jacket has some stains although you cannot see them at all on the dark olive green shell; other than that, this jacket is in great condition and would probably survive a nuclear bomb, it’s so well made! It looks great! The size, as mentioned above, is a Men’s XL and the entire jacket is made of %100 Polyester
