The whole part is simply sophisticated and high quality. All seams are perfectly executed, the gums are designed appropriately, ie sewn a little stronger and are at the leg ends slightly weaker rubber on the abdomen.
The trousers in black color looks very noble. It shines a little, shining like silk or as part of synthetic fibers. On a synthetic fiber, I also first thought when Tencel (R). But this is the brand name of a company, the fabric is actually Lyocell and is made of cellulose (ie plant) fiber. Looks great, but probably even better properties such as cotton because the fiber is said to have a high dry and wet strength and also absorbs moisture well. Furthermore, the substance is almost wrinkle free. Furthermore, a little spandex is material available which makes for great freedom of movement.
Class of Product five stars!
