I bought 3 more…
Special Size: Midweight, Size: 34W x 28L, Color: Dark Midnight Wash
How can you go wrong with great fitting, comfortable, jeans that look great and cost half of most jeans? I just purchased 3 more pair.

Good if they fit
Special Size: Midweight, Size: 30W x 30L, Color: Dark Midnight Wash
The jeans are great, once I got the right size, but these I brought back to Whole Foods and got charged anyway because Amazon never got them back!! But cheaper than Levi’s

Important fit information
Special Size: Midweight, Size: 34W x 30L, Color: Tinted Medium Blue
Be aware that these jeans are loose fit, not fitted through hips and thighs. Excellent quality, well made, great value. But if you are not overweight, if you have a trim build you will NOT like these. They were very baggy and loose around my husband's butt and thighs, so we had to return them. However, if you have a more generous build under your size 34 waist you WILL like these, and the waist has some stretch. I removed one star for calling these fitted through hips and thighs. They're not.

Great fit and value for quality jeans
Special Size: Midweight, Size: 42W x 30L, Color: Tinted Medium Blue
For once I bought a pair of jeans that are super comfortable and feel like I’ve had them for years
I had to return for a shorter size which was no problem and they now fit perfect
Very good quality material like Levi’s or Wranglers not like inferior substitutes
Great value for a quality product
