Cowboys need a thicker, long-wearing material to resist scratches from bushes, a material that can get wet then dry out in the sun without shrinking.
The first commercial-quantity denim manufacturer is generally considered to be Levi's who created the 5-pocket style including a small coin pocket. Levi Strauss knew about the heavy twill cotton material made famous in Nimes, France and in French, "from Nimes" can be translated into "de Nimes", or denim.
Denim jeans now come in many styles, but for cowboys a boot cut is needed where the width at the bottom of the leg will fit over a cowboy boot. Traditional styles, especially in the US, are starched. Starching can make the jeans stiff until work in, but also resist dust and dirt.
Traditional styles have roominess needed for flexibility and sit at the waist. Now, slim fit styles, high-waist and low-waist options, not to mention dark and ligther washes and just about every wash in between, are all popular.
Over the decades Wrangler became closely associated with cowboys and rodeos, and Wrangler makes all these styles available, and Wei's stocks almost all of them.
Modern jean styles may include 1-2% spandex or other stretchy material to make the jeans even more comfortable. Typically jeans are 98-100% cotton but some styles include polyester in the material. Quality cowboy jeans, like the ones we have, are not only stylish, but they’re rough and rugged and ready to ride.
