Pro Race Day Singlet
Built for the days that matter most.
Introducing the Pro Race Day Singlet — our pinnacle performance piece, designed for runners who demand everything from their race kit without compromise. Lightweight, technical, and precision-built, this singlet was created to disappear while you perform at your best.
Every detail has been refined with intention. From the barely-there feel of the fabric to the clean, understated branding, the Pro Singlet is engineered for movement at speed. Confident without being loud, sharp without trying too hard — this is race wear designed with a modern runner in mind.
The artistic finish gives the singlet its identity. Fluid, energetic, and subtly expressive, the design captures the movement and emotion of race day itself. Distinctive enough to stand out, refined enough to remain timeless.
Race-Day Performance: Constructed using an ultra-lightweight technical fabric designed to maximise breathability, airflow, and comfort when the pace increases. Soft against the skin with a barely noticeable feel during effort.
Engineered For Speed: Cut with a streamlined athletic fit that moves naturally with the body while remaining light and unrestricted from first stride to finish line.
Minimal Branding: Finished with a subtle blurred NS logo on the left chest, understated Negative Split detailing on the rear neckline, and a minimal NS mark on the back right for a clean, elevated aesthetic.
Second-Skin Comfort: Sweat-wicking, fast drying, and exceptionally breathable to help regulate temperature through hard sessions and race conditions.
Refined Construction: Smooth seams and precision finishing reduce distraction and allow the singlet to sit effortlessly during movement, whether over 5K or the marathon distance.
Designed To Be Remembered: Built not just for performance, but for the feeling attached to race day — the early mornings, the nerves, the energy on the start line, and the moments that stay with you long after the finish.
