Suprisingly great jeans.
Special Size: Midweight, Size: 29W x 32L, Color: Grey Wash
Love the fit and style of these. The waste is abnormally small, I purchased a 29 but also 30 would have been better. The rest of the fit is great, color is great, good mix between stretchy and stiff.

Too baggy! (UPDATE): Bought this style of jeans again and they fit great!
Size: 31W x 30L, Color: Tinted Light Wash
These jeans are too baggy for my liking. Edit: I purchased more jeans of this style recently again and for some reason they fit a lot better to my liking than before when I first left the initial review for this. I have updated my review from 3 stars to 4 stars now. I purchased the black, grey, dark wash and tinted medium blue, and all 4 had a good fit on me. My original review stated that it was too baggy but the 4 jeans I just bought had a fitted look which is what i prefer, not too baggy and not to slim/skinny. I want to point out that the fit varies from the color choices. For example, the black, grey and dark wash jeans, i went with a size 32x30 because 31x30 for those colors were too tight/slim on me and for the tinted medium blue, i downsize to 31x30 because 32x30 for this color is too baggy. So buy the size you usually wear and if it's too slim or baggy then send it back and size up or down. Buying jeans on Amazon, i feel that you will have to buy a few different sizes and see which one fits you the best and then go from there. Edit (3/7/26): sizing is very inconsistent. So my previous edit above stated that the jeans I recently purchased fit great on me, and that's true, so I decided to buy another jean, same color and same size, this time the jean fit way too small/tight. I feel like amazon needs to do better quality control on these jeans. How does 2 pairs of the same jeans/color/size have such an inconsistent in size/fitting to it!

Great fitting jeans just as nice as any name brand you can buy !
Size: 34W x 28L, Color: Tinted Light Wash
So I have been on a weight loss journey and the Amazon jeans have been my go to. For one to me they are just as nice as any of the name brands. They fit well are comfortable and honestly they are all I have purchased for a few years now. I’m also super short and this is one of the few brands I can find in a 29 length and that also saves me money since I don’t have to take them to a tailor to be modified. Material is nice to the touch nice thickness and has all the pockets you would expect in a blue jeans. Again great value for the money and this is about my 5th pair of these in various colors. I highly recommend give them a try and you will be hooked !
