Buena tela
Color: Black, Size: 30
A mi hijo le encantan. Mi hijo es normalmente talla 32, pero en este tipo de pantalón es 30 debido
A que se lo coloca en la cadera.

Super big
Color: Light Grey, Size: 36
Bought 4 pairs of these shorts and had to send all four pairs back. They run very big, in the waist and overall. They are super long. My son is 5'10" and he said they were way longer than he wanted them. They appear to be good quality, heavy material jean shorts. I would recommend sizing down if this is the look you're going for. And they're a little pricey.

Shorts
Color: Green, Size: 40
With exception of the seeming low quality zippers and fasteners, the shorts are nice in fit and style.

Pretty good overall just a little long
Color: Light Grey, Size: 40
Nice material and nice baggy fit just a little too long it’s almost at my ankles so I got them cut down.
