Great quality and price, true to size, and comfortable fit
Size: 32W x 30L, Color: Medium Vintage
Nice jeans--very close in quality to my more expensive Wranglers. And they run true to size, which is a real bonus in today's unpredictable clothing markets. The flexibility of the material makes them very comfortable, whether you're walking or sitting. Good job, Amazon Essentials!
