If someone asked you what is the most important piece of clothing you have in your wardrobe, what your answer would be? Most likely, you will answer him talking about your collared grey shirt or your favorite cargo pants! But what if I asked you “what is the piece that combines the comfy and life-saving feature that you have in your wardrobe or your laundry right now”? probably, you will answer “my briefs”, and this is true!
