6'1" 280+ with a middle, and 3x is perfect
Size: 3X-Large, Color: Antique Indigo
Naturally, this arrived stiff and the arms were a little long, but a hot wash and hot dry softened it perfectly and brought the sleeves up just enough. Jean jackets just have to break in. I slept in it last night to form it to my body although my wife thought I was nuts. These aren't warm jackets, but if you're my size 3x will leave just enough room for layers. Of course, the jacket will become a best friend like all the others have. It'll just take some time. I've seen complaints about the buttons and, yes, they'll also need to break in too. But they will!

Like Steve McQueen, all I need's a fast machine...
Size: Medium, Color: Vintage Indigo
I was very impressed by the quality of the Vintage Indigo (distressed) jacket I received. Much heavier denim than Levi's, rugged stitching, classic fit that is also much better than the relaxed Levi's available on Amazon. The inside pockets are generous and sturdy but have no closure flap so if you bent over enough I suppose things could fall out. This jacket is pretty bombproof if you ask me and at half the price of Levi's. I only wish that they made this in size small, which I can't find anywhere. I am 5'9" and 170 lbs, athletic build. I like a high and tight fit on these like Steve McQueen would have rocked, the shoulders and sleeves on this medium size are a bit oversized, the body is just a tad more relaxed and longer than I would like. Most guys would probably be very pleased with this medium. It would work very well over sweaters and such. Update: I ordered the Lee Boss Man vintage style jacket in Medium, it's much tighter fitting than this Wrangler and the vintage wash is much more convincing. The Lee is a much trimmer fit, tight across the shoulders and through the sleeves, slim on the body. It's more the Steve McQueen look I was searching for so it's a keeper. No room for sweaters under the Lee and the denim is much lighter weight than the Wrangler. Lee's the one for me. This Wrangler is very good quality but not quite the fit for me so it goes back. Thankfully Amazon makes returns free and easy so you can try every brand.

Size & fit great
Size: Large, Color: Vintage Indigo
The fit of the jean jacket was as described. I did order a large. I am 5'11'' The sleeves were Not long they were the proper length and came to my wrist as they should have. The color was a little darker than the picture but still a nice washed-out blue. Looking forward to years of wearing this jacket. The jacket is high quality with excellent stitching. I am a consumer and was not compensated for this review.

Runs a little large
Size: X-Large Tall, Color: Antique Indigo
Awesome jacket! I am a vintage Lee Rider jacket man since high school. All Made in USA from denim Made in USA. Oldest from High School. Think I bought a Wrangler jacket once and it was not fitted like a Rider, boxy and baggy. Returned it. Wanted to try a Wrangler or Levi jacket after wearing Lee jackets for over 50 years. Modern Lee are Lee by name. After reading a 100 reviews the Wrangler reviews were consistent. The Levi reviews were all over the place, small, large, thin, thick, all cotton, stretch, made no telling where. Ordered this jacket. Ordered a XL Tall. Usually wear a XXL. But running large was a consistent comment. Sized to fit a hoodie under. Built odd, 48 jacket, 37 shirt sleeves, 36 pants are loose fit. The sized down jacket fits a little loose. May shrink down a little, washed twice yesterday. But like all Bangladesh made clothes I have owned the quality is equal to my 70’s, 80’s, and 90’s Made in USA Lee Rider jackets. The denim is top quality, the stitching is even and well done. Not as slick as my Diamond Gusset denim jacket on finishing inside, think 700.00 suit coat quality, but equal to any of my five Lee jackets. This is a Tough Wear and not an Italian suit coat. Living in Houston we only see a month or two of jacket weather a year. Wearing shorts and tee shirt today. So stores do not stock year round. Amazon was a gamble on size and quality. Looked before ordering, no stores had jackets in stock after first of the year to try size and fit. I got lucky. Fit like a XXL Lee Rider or Diamond Gusset. Quality of denim and construction are top notch. Much recommended, just order down on size if you are borderline on sizes.
