Bill Bowerman pushed many runners on to greatness in his coaching career, and his namesake running top will do just the same for you. The Nike Sphere Men's Bowerman Top is a Sphere Dry™ workout top specially engineered for dry, cool workouts. The body-contoured design features open, raglan sleeves and ergonomic side seams to minimize chafing and irritation. Mesh insets assist in ventilation and moisture control in strategic locations like the back, upper chest and sides. The design benefits from 1/8" exposed reflective piping and the Nike FIT trademark. Body: Sphere Dry™ 94% polyester/6% spandex piqué. Mesh: Dri-FIT® 100% polyester. Imported.
