Perfect for my husband. So comfortable and look like regular jeans like he used to be able to wear. All his life he would only wear Levi shrink to fit, but in last few years they were too stiff and uncomfortable due to injuries and poor health, so has been wearing stretch pants and hating them. I ordered these not expecting them to work, but they fit him perfectly and are so comfortable I ordered him 2 more pair. He is so happy to be wearing blue jeans again. One caution, other styles of this brand do not fit the same as these jeans, I ordered another and have to return them and order 1 or 2 sizes bigger than the jeans

Good quality, stress, jeans I recommend them

Size: Large, Color: Beau Blue

Great fit I never seen jeans at stretch but they are comfortable. I tried to order a 30 for some reason they gave me a 36. It’s a little too big but I guess I’ll watch hot water. The waist will shrink. I’m gonna try to order another pair, but I want them in 34 not 36 and it’s giving me a problem when I try to order 34 pops up 36. I’ll figure it out but other than that nice jeans good quality
