Just got these all cotton dress pants in sort of light slate blue (blue-gray?) color. My first pair of Incotex. Excellent! I brought them to the tailor for hemming and asked him about that loop in the front near the waist. I noticed it on a pair of Brioni suit pants and wondered what it was for. He said it was to put the clasp (?) through to prevent sliding up or down of the belt. Of course! Great idea! How many here already knew this? Be honest.
