Awful
Size: 32W x 34L, Color: Black
These are the least comfortable jeans ever. Not stretchy. Not lightweight. I feel like I can barely move in them. Don't make the same mistake I made. I wish I never bought these.

Amazon essentials jeans
Size: 36W x 30L, Color: Stone Medium Wash
Wasn’t sure what I was going to get for such a low price, very happy with it. When I told my wife I bought a low priced Amazon essentials pair of jeans she said I shouldn’t wear them when I go out, just around the house and yard. After they arrived and I tried them on she changed her mind, said I should get several pairs. They fit perfectly and look great. Always appreciate a good deal!

Great jeans from Amazon's own brand. Comfortable pricie and fit.
Size: 30W x 30L, Color: Stone Medium Wash
I was surprised to find that Amazon has its own line of men's jeans. I rthought I was taking a chance buying the pair that I did. They turn out to be a terrific buy. I highly recommend Amazon's men's jeans. I intend to buy more.
