Men's XS size. I think it has a slightly relaxed fit. I'm a woman and usually wear a size L. It feels just right. I bought it, but I haven't had the chance to wear it, so I've just been storing it. Only tried it on, but there are some fold wrinkles. - Brand: MOUNTAIN HARDWEAR - Material: Fleece - Size: XS - Color worn: Khaki - Pocket: Chest pocket (with zipper)
