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.

Extremely temporary solution to pants
Size: 33W x 32L, Color: Stone Medium Wash
Very comfortable and good fit. But...they're extremely fragile. I bought three pairs one after the other as each failed. Typically only got a month or so of wear-time before a giant rip would appear along a major seam.
Great if you need a quick/temporary pair of jeans. Terrible if you plan to use these jeans for more than a couple of wash cycles.

Perfect fit and stretch, durable and priced right
Size: 38W x 34L, Color: Tinted Dark Wash
Great pair of jeans for the money! Fit is spot on. They’re durable and comfortable as well, there’s a slight stretch to them making them easy to work and move around. My wife tells me my butt looks good in them too! The selection of colors is very cool. If you’re looking for some budget, slim fit jeans, you’re in the right place!
