Nopinz is touting its new Hypersonic Base Layer as one of the greatest aerodynamic apparel advances in recent times, harnessing years of the British brand’s own research and development, combined with hours of wind-tunnel testing by former World Hour Record holder Alex Dowsett, resulting in a secret weapon that’s optimized for riders who operate in the 40 – 50km/hr window.
“Data shows that pairing the Hypersonic Base layer with our Pro-1 Evo Speedsuit saves an average of 10w with maximum saving of 16w at 50kph,” claims Nopinz.
“The Hypersonic Base Layer is designed to be worn beneath a jersey or speedsuit – so how does it affect aerodynamics? Simply put, the textured Superstripe fabric on the sleeves and raised trip seam on the lower back project through the outer garment to create a low-pressure wake that reduces drag. Think of it like a car spoiler. In fact, it comprehensively beats the competition over a range of speeds and yaw angles. Breathable fabrics provide cooling. A neat front pocket is handy for storing a key or race radio,” adds Nopinz.
The Hypersonic Base Layer is available in seven sizes in white or black for £139.99.
KEY FEATURES
- Lightweight, aerodynamic base layer designed for WorldTour riders and now available to all. Refined and tested at the Silverstone wind tunnel by former hour record holder Alex Dowsett. Results ratified by WorldTour teams.
- Average aerodynamic saving of 15w over the Pro-1 Evo Speedsuit with no base layer, with a maximum saving of 16w at 50kph.
- Can be used beneath most close-fitting garments to provide an aerodynamic shape on the surface. For best results, pair with an outer layer that is ideally smooth or lightly textured such as the Pro-1 Evo Speedsuit.
- in the sleeves trips the boundary layer of air flowing over the rider for significant watt savings.
- Raised trip seam on the lower back helps to cut drag over a range of speeds and yaw angles, but optimised when riding between 40 – 50km/hr.
- Breathable fabrics in the main body maintain core temperature to minimise overheating power loss.
- Low-profile gripper bands ensure perfect placement in the riding position.
- Front pocket to store key or race radio.
- Seven sizes to choose from.
