My favorite ultimate trackpants would be Adidas Black Nylon 3-Stripe Pants (preferably them being "popper" pants as well; I also love the color black). My second favorite ultimate trackpants would be Asics Black Nylon Pants (with the drawstring cord), because I like rooting for the underdog sometimes. (I will say this: the color's a pretty big influence on me on whether or not I buy nylon pants from either Goodwill or online, because black has ALWAYS been my favorite color, followed by dark blue/navy blue as my second favorite color and purple as my third favorite color).
