The carbon colorway gives this polo a more neutral, boardroom-friendly look than the red version, while still carrying the same embroidered Ohio State chest logo. The 92% polyester / 8% spandex blend adds a bit of stretch that a pure-poly polo doesn't have, which shows up in how it moves across the shoulders.
That stretch also makes it a reasonable pick for anyone who wants something wearable beyond the stadium (client meetings, travel, a round of golf) without it reading as overtly branded fan gear. It's offered M through 4XL, and at $68-$72 it sits at a noticeably higher price point than the standard red polo, which is worth acknowledging directly since shoppers comparing the two will notice.
