The jacket is made of very nice material. It's not real leather, but it's very soft and smooth. This jacket has two layers so I feel very warm wearing it. On the other hand, it's quite heavy (about 3 lbs), so if you're looking for a lightweight jacket, it may not be the one for you. About the size, I'm 5'7 and weigh 145 lbs, and size small fits me perfectly. My shirts sleeve is 32-33 and this jacket has about the same sleeve length. Overall, I'm very happy with the purchase. Will definitely recommend it to anyone looking for a budget "leather" jacket.
