#1 Winterwear Choice
My favorite jacket I own. This jacket is not only one of the most stylish articles of clothing I have, but perhaps one of the warmest. When I bought an XL I got an XL, it fits perfect. Its heavy for a denim jacket, but that means it is built with quality. Not only does it have a clean aesthetic, but it is extremely utilitarian: If you're getting a jacket, you're getting it for a purpose. This jacket serves that purpose, in fact it serves multiple. This jacket has deep pockets, so your valubles don't slip out while standing or sitting. The price for this jacket is phenomenal, and almost unreasonable for the manufacturer compared to the actual quality you get. The materials to make this jacket may be inexpensive or cheap, but they certainly don't don't look or feel that way. If this jacket ever tears or gets ruined, I'm just going to buy another honestly. I highly recommend this jacket to anyone who wants quality, warmth, durability, aesthetic, and a budget conscious choice compared to designer brand apparel.

Great Quality
My son Loves this Jacket. He specifically asked for one for Christmas and this one met his every expectation. It is great quality. It is thick and warm without being too bulky. I sized up for him since he is a growing teenager and it still fits great and he will be able to wear it next winter too if he wants.

Cotton as Stylish as Snow
So far, after only wearing it a handful of days, I have already fallen deeply in love with this jacket. With its quality fleece jean material and stylish look, it's arguably climbed at record speed to being my favorite winter jacket thus far. It won't exactly cut it for the days of extreme cold, but it's practically perfect for those high 30s to low 50s degree Fahrenheit weather! The cotton on the inside is both soft and warm, and the overall fit of it hits a perfect sweet spot of being weighty without feeling too hefty or dragging on the body. The pockets aren't the deepest in the world, but with four of them, they'll be more than able to carry an decently sized arsenal of your everyday items. It lays on nicely, and is able to be worn with an extra layer or two underneath, in case a bit of extra warmth is needed. The only caveat that I could give it, hence why I gave it 4 stars instead of 5, is that if you choose to dawn on clothes that are rather lint susceptible, this jacket will be a direct enemy to it. But that is where the criticisms start and end, and is why I wish there were a way to give a product a 4.5 stars review here on Amazon. Otherwise, this is a must buy for anyone looking for a winter jacket that packs a bit more visual finesse than a typical puffer jacket. If only I had the sense to buy a winter jean jacket such as this one sooner rather than later!
