Definitely NOT the COLOR that’s advertised but not bad
I got this for my son for him to have his 1st official “dressy” coat for certain occasions. It will do for the price, but as I said in the description, it’s definitely not the color that’s shown in the advertisement. Its also not taken in like the picture. But not bad. It’s more of a camel color than a khaki like the advertisement. My son is 5’9 and has a slim build, I bought a L because he’s tall and this fits fine to be honest. I want him to be able to grow into it next year as well. If you have long arms you may wanna size up.

Nothing i wrote my comments above a statement above
Size: XX-Large, Color: Navy Blue
This item was not good quality, so I decided to not not use. It came pretty much wrinkled and folded in some package. And once again, it was not good quality was all wrinkled up you had to Send it to the cleaners to straighten it out and it didn't fit very well. It just wasn't there very good quality, kind of heavy, so so\n I'm not sure if I'll return it or just donate it to the local church. Thank you art cruz

Fantastic product... fantastic fit !
Size: X-Large, Color: Black
First off, China got this product from their country to ours, then to my hometown.... faster than my own post office could get it across town after much bickering. So... thank you to the Chinese. Complaints about America being better... then start doing better. Secondly the coat was far superior than I even suspected. It fit well and I cannot wait until cooler weather to break it out ! Again... thank you China ! Highly recommend this product.

Once You Try Them, You'll Buy More!
Size: 46W x 36L, Color: Stonewashed
I'm tall (6'3"), and when I was young, I used to be thin as a rail (though decades of three squares a day has changed that). So finding jeans that fit well has always been challenging. A long inseam (36") made purchasing jeans at retail stores an exercise in futility. So for many years, I bought my jeans from cataloger Eddie Bauer. Oh sure, I would try other mail order firms from time to time, but never found a pair of jeans that fit comfortably. I'm no longer young (Daddy was feeling his oats when Ike was in the White House) and much of the vanity that plagued me in my youth has dissipated. Be forewarned as you continue reading, that comfort, not appearance, now tempers all my purchasing decisions. It was time to purchase a couple pairs of jeans, and because Eddie is getting awful pricey, I decided to see what was being offered here on Amazon. The price was right, and the reviews were good, so I ordered a pair of these "just to see". Boy, I'm I glad I did!! These jeans are designed for guys who want comfort over a full range of movement. First, the material; although the description says "flex denim", it is not "stretchy" (remember double-knit?). I think they may be referring to the fact that the material is a bit lighter weight than your average jeans, thus avoiding much of the stiffness. The material reminds me very much of some painter's pants I owned years ago; soft and very pliable. Now for the fit; generously cut (though not baggy) in the seat and crotch. No binding of your manhood when you sit or squat! Plenty of room in the legs too. The waste is cut high enough so your belt sits comfortably above your hips, avoiding the embarrassment of plumber's crack when you're on your hands and knees, bent over without your glasses, looking for that damned little screw you dropped. Finally, the inseam length is also generous. When you're sitting with your legs crossed, these pants won't be jacked half-way up your calf. So, in conclusion, if you're trying to make a fashion statement with hip-hugging, tight-legged, twig & berry squeezing pants, you will be sorely disappointed with these jeans. But, if you're a working man, looking for a well-fitting, comfortable pair of britches, I'll bet you a fresh tin of Shinola and a Moon Pie, that you will appreciate slipping into a pair of these jeans!! I just ordered two more pair!!
