Huub Thermal shirt Aero Bridge

Designed to be worn under any smooth-sleeved cycling jersey, road speed suit or triathlon suit for added speed.

The original Aero-Bridge Undervest. Developed at the Silverstone Sports Engineering Hub and Derby Velodrome with some of the world's top engineers and cyclists.

This base layer has lit up the Olympics and made nations wonder why they hadn't thought of it. It's so effective that everyone wants one! It's the product that has frustrated some cycling team leaders... In fact, we really should have called it the FTL undervest. But this speed secret is now commercially available and not just for wealthy cycling nations.

Developed to create a unique surface reaction disrupting the boundary layer around the body, the Aero-Bridge Undervest offers the most effective solution for significant speed gains. Leveraging HUUB's patented 'Aero-Bridge' technology, it's another first for HUUB, available to all athletes to help unlock their potential on the road or track.

The base layer creates dynamic surface reactions to disrupt the boundary layer of air flowing over the body's cylinders (biceps and forearms). The result is significant aerodynamic savings, even greater than those offered by traditional textured fabrics.

The Aero-Bridge technology works by stretching a smooth fabric over a textured fabric (the raised ridges create a material suspension like a suspended bridge) to disrupt air flow by the ridge and then further modify it through the suspended fabric, causing tiny air particles that enhance the movement of the boundary layer. Different ridges can be used for different speeds.

With our new exclusive 'Aero-Bridge' technology, the textured fabric with varying spacings, depending on your speed, is worn under the suit or jersey. This combination allows the undervest to deliver the secret that helps nations, individuals, and record holders reach their best performance.
