I was not impressed at all by the Jackson Amazon.com Exclusive Men's Original Fit Jeans for the following reasons:

1) Waist Size: I got a 34" waist and they were at least a 36".  Unless you enjoy wearing pants that are too big for you or playing roulette through mail order to guess what size you really need, you almost have to try these pants on in a store to figure out what you need.
2) Fit: The pants are cut really weird such that there is almost zero room in the butt.  I am thin (6'6" - 195 lbs) and even I had trouble fitting my bony butt comfotably into these pants.  I don't know how someone with more normal proportions would ever be able to wear them.  Maybe that's why the waist is so big - you need room for your butt to ride up...
3) Pant Leg Size: The legs are gigantic!  Granted I usually wear a slim, but I was swimming in the pants.  Not sure what pair of pants are shown on the Amazon page, but the pant legs are much wider than the picture shows.  In addition, the pants leg are somewhat long for a 32" inseam.  I normally wear a 36" leg and they were not laughably short.  Not sure if this is a drawback or simply a note that the listed sizing is not what you would expect.
4) Construction: Although the material is nice denim and is soft, there are flaws all over the jeans from poor construction - misaligned seams, stitching that isn't straight, threads hanging out.  I'm not sure how these pants retailed originally for $60 since the quality is atrocious.
5) Selection: Very limited - so I hope everyone has a 32" inseam because that's all the selection Amazon offers.

Obviously I didn't like the pants.  Not sure what else to say...
