Love these jeans
Size: 34W x 30L, Color: Black Rinse, Size: 34W x 30L, Color: Black Rinse
Nice jeans. THe fit is great, the material is kind of stretchy, and the black color is true black not a faded look. Hard for me to find a good pair of jeans but these I love.

They feel like cardboard
Size: 36W x 29L, Color: Medium Grey
I kept these hoping to replace a denizen slim 216 that I can’t find anymore. These are not as a soft and rather quite stiff, maybe due to the recycled content. They might do for the occasional trip out of the house but I’m not impressed and glad I didn’t pay full price.

All Day Comfort
Size: 34W x 32L, Color: Medium Grey
If you like the trim look of slim-cut jeans, you will love these. The silhouette is near perfect without veering into skinny jeans territory and the extra length make mine perfect with boots. The denim is good quality and the stretch fabric retains its shape, resisting the baggy look after multiple days of wear. The grey color is just right without the unnatural whiskers and wear-lines added by other brands. I love these jeans and look forward to many years of uses.
