Hypersonic Mk2 Base LayerWhite
£159.99
The fastest base layer we’ve ever produced. Combining our latest Speedcell aerodynamic fabric with enhanced cooling and a refined race ready fit, the Hypersonic Mk2 Base Layer delivers wind tunnel proven performance plus a simple upgrade path for existing Hypersonic riders.
Limited to just 100 base layers in white.
The Hypersonic Mk2 Base Layer has been completely redesigned to deliver greater aerodynamic performance and improved thermal regulation beneath your race suit.
At the heart of the update is our new Speedcell fabric, a premium aerodynamic textile commissioned specifically for the Hypersonic Mk2 range. Its unique textured surface is engineered to optimise airflow and reduce drag across critical areas of the rider’s body.
The fit has also been refined with a shorter cropped construction, removing material around the torso to improve cooling and comfort during high intensity efforts. The result is a base layer that works more effectively beneath your race suit while helping regulate temperature on race day. The handy radio/phone/key pocket has been aerodynamically placed with the potential to further enhance aerodynamics.
Finally strategically placed Speedcell panels across the shoulders and upper back target one of the most aerodynamically important airflow zones, helping control airflow as it transitions across the rider and race suit.
Wind tunnel tested against the previous-generation Hypersonic base layer, the new design delivered an average aerodynamic saving of 11.6 watts, with peak gains of up to 13.6 watts at race speeds of 55 kph.
For riders already racing in a Hypersonic Speedsuit (or equivalent), the Hypersonic Mk2 Base Layer offers a simple and cost effective way to benefit from our latest aerodynamic development, delivering measurable performance gains without replacing your entire race suit.
Designed and manufactured in the UK, the Hypersonic Mk2 Base Layer is built for athletes seeking every possible advantage.
