The fit is pretty terrible. Bunchy in the crotch. Lack of inseam lengths so they can be either too long or too short depending on your height. I would have rated these a 3 overall because they are what you pay for. Passable cheap jeans, but honestly you're better off shopping cheap department store jeans. I give it a one for durability. Only a handful of wears since September and they've torn at the stitching under the zipper just after a very light lunge. Buyer beware .

Can't beat it!

Size: 30W x 34L, Color: Black-heavyweight

These pants are a little to snug on waist but i only really notice this problem on black jeans regardless of brand, other than that These a verry comfy zipper work well haven't had any issues I wear these once a week so obviously I wash them once a week, color hasnt faded much at all. Compared to levi I think amazon has them beat in Price, Quality, Durability, Color Fading. You cant go wrong with these.
