WranglerMen's Flame Resistant Ranger Pant

Great fit and the material is thick enough to last awhile. Which is like gold nowadays. Everything is now "stretch" or "summer" or 100 other marketing terms which simply translate to "thinner, because it's cheaper".

They're cut well; allowing full range of motion. One issue with them is that they fit small. That is to say that I would suggest getting a size larger than you normally would.
