They run short
Color: Khaki, Size: 36
They run short and then when you wash them they get even shorter I wash them in cold water and I don't dry them all the way I pull them out and they still are short

Comfy pants!
Color: Camel, Size: 34
These elastic waist pants fit my son perfectly. He has difficulty with buttons and zippers so this is his best bet in order to look a little more fancy. The fit very well and are true to size. They are a little thin, but they look nice.

NICE AND STRETCHY
Color: Navy Blue, Size: 42
These pants are made of a material that seems durable and is definitely comfortable, and they have a stretch band at the waist that can comfortably accommodate many different belly girths-- from slim to portly. The waist also has a drawstring. I'd call these light weight pants, as the material is thin. They aren't baggy at all and fit the natural contours of an average male physique.
The pants have two fairly deep front pockets and one small rear pocket that can easily fit a regular-sized wallet. But, I would not recommend carrying a wallet in the rear pocket, as, due to the depth of the pocket being only as deep as the wallet is long, it might slip out as you move around, sitting and rising.
If nature calls, and you need to pee, you will have to pull your pants down and excite anyone in the immediate vicinity, as there is no opening, either buttoned or zippered, in the front of the pants. So, in that respect they are kind of like sweatpants. I'd call these pants good for inside the house or wearing on the street.
I like them despite the lack of a fly, so I give 5 stars. I see lots of Chinese, Korean, and Japanese guys around who like to wear this type of pant, but these fit nicely for generally larger and more robust Caucasians type physiques as well. You don't have to worry about a belt or a broken fly zipper with these.
Of course they are made in China, but due to their vast experience selling clothing to Americans, the manufacturers are well acquainted with big masculine American bodies and their needs.
