Fit me even better than I was hoping.
Size: XX-Large, Color: Beau Blue
I was all but convinced upon receipt I would be sending these back but they fit beautifully. The trick is understanding what the directions are trying to tell you. I’m 6’4 with a 40 inch waist on traditional jeans (regular fit). I selected 2XL because my feeling was I would want and need a waist line that would fit me but not constrict me. Admittedly my regular fits were getting close to not fitting as good anymore so I felt 2XL would give me that “extra” my regular fits were no longer affording me. Comfortable at the waist(not too tight) and they fit me nicely all over. Perfect length. Colors look great too. The pictures shown are accurate. I’ll be ordering more. Give these a try! Definitely worth the money.

amazing pair of jeans!
Size: XX-Large, Color: Dirty Blue
im 6'2, 280 currently , bought a 38/32 pair of, these jeans and will instantly look forward to buying more, just for comparison , the same day i got these i tried on a pair of levis i had just bought as well, the Levi jeans i got were also 38/32, and they were the 501's which are stretchy, but maaaan, let me tell you, the difference between those and these are night and day, these feel like i can run a mile in them and do whatever activities i choose to, its stretchy in all the right places, the crotch area isnt tight at all, these are incredibly breathable and in comparison to the levi's price , these are cheaper by $15 and they weren't even on sale, unlike the levis which were on sale by 15% and STILL costed $50. Will buy more ASAP. 10/10

stretch jeans
Size: Large, Color: Dirty Blue
These jeans because they are very comfortable. They stretch just the right amount without binding. I am female but wear men's jeans. These jeans ride lower so sometimes slide down. I ended up solving that issue by ordering a second pair in a smaller size. Worked perfectly. They stretch so no problem there, and now they stay up!

very comfortable, good looking
Size: X-Large, Color: Deep Blue
Perfect for my husband. So comfortable and look like regular jeans like he used to be able to wear. All his life he would only wear Levi shrink to fit, but in last few years they were too stiff and uncomfortable due to injuries and poor health, so has been wearing stretch pants and hating them. I ordered these not expecting them to work, but they fit him perfectly and are so comfortable I ordered him 2 more pair. He is so happy to be wearing blue jeans again. One caution, other styles of this brand do not fit the same as these jeans, I ordered another and have to return them and order 1 or 2 sizes bigger than the jeans
