Type of trousers

I try not to drop name brands in posts because I do not want to be in violation of any guidelines, but in this case I feel I need to ask about a brand of trousers. This may sound like a silly question, but are Sansabelt trousers marketed toward a certain age group or type of body build? I found an inexpensive pair which are my size but I never even seen them on anybody under 50, and also seen referees wear them. Should I snag them up even though I am only 38 years old, and a 32 inch waist?
