No they don't come with any padding, and compared to the Humvees, the material is much thicker/stiffer. As the description states they are made from robust stretch cotton twill and are teflon coated. So despite the great price, if you prefer the thin nylon of the Humvees, these probably aren't what you are looking for.
They look like they'll be very hard wearing shorts, perhaps more suited to touring as they look far more presentable off the bike (they seem to be a much neater cut than the Humvees, not so baggy). I think they'll fare better in the rain too, though I'm not sure they'll be ideal shorts for wearing in hot weather.
