Would buy again
Size: 36W x 34L, Color: Tinted Light Wash
These blue jeans are comfortable, fit as expected, and are suitable for everyday wear. The material feels durable without being too stiff, and they hold their shape well after washing. The color is true to the listing photos and hasn’t faded so far. Material is comfortable and not too thick, and stretch level is minimal. They’re not premium designer jeans, but for the price, the quality is solid and they get the job done. I would recommend these if you’re looking for affordable, reliable jeans for casual or work use.

Great jeans
Size: 32W x 34L, Color: Tinted Dark Wash
Super comfy, fit true to size, and stretchy enough to wear day to day. Great value and they look super clean. Athletic fit is great for bigger thighs to keep comfortable and not cut off blood flow haha

Thick, durable jeans for a good price!
Size: 34W x 34L, Color: Tinted Dark Wash
I bought these for my son. They fit well - true to size. They feel thick and durable. He says the fabric is a little stiff, which makes them wrinkle, so he doesn't wear them as often as some other jeans.

They are dark blue and are great especially for the price.
Size: 38W x 28L, Color: Tinted Dark Wash
They fit true to the size and the dark blue color is perfect...!!! I did wash them in hot water and put them in the dryer on low temperature before I wore them and they fit perfect. And I am 5'6" weight about 215lbs. I bought the 38 waste and 28 length and athletic fit stretch and they do stretch and I absolutely love them...!!!
