7 belt loops!
Color: Original Stone, Size: 36W x 32L
Finally Lee is making a pair of jeans with seven belt loops! And in loose fit! 50-year-old men with Dad bodies should not be wearing skinny jeans. Anyway great pair of jeans, size wise it's the same size as all the rest of my jeans. Should be good for summer work. The denim is a bit on the thinner side so I don't know how long they will last but they're good for now

Great purchase

Fits perfectly, the color and fabric texture are great. Personally I prefer buttons to zipper but can't complain about that

Good jeans
Color: Retro Stone, Size: 36W x 34L
The jeans were delivered in a rather thin plastic bag; no box in an area that could have been exposed to bad weather. There was a very small imperfection in the bottom of one cuff that was not caused by the wrapper being flimsy. Not worth sending back, but packaging should have been bettet.

Old school comfort
Color: Retro Stone, Size: 38W x 34L
Old stone wash carpenter jeans. Fits great and very comfortable. Correct size and length. Will buy again. Had a pair of these several years ago and forgot how good Lee jeans fit.
