  • The world’s fastest tri suit. Updated, in collaboration with professional triathletes.  

    The Aero 2.0 tri speedsuit is our new and updated top model for triathlon with the perfect combination of aerodynamics and fabrics optimized for hydrodynamics.
    Developed by the engineers at NTNU in Trondheim and tested in wind tunnels, the Aero concept proved to safe precious watts at individual time trials in the sport of cycling and we adapted this knowledge designing the Aero tri speedsuit. Eventually, this is proven to be the world's fastest and most innovative suit in the market dedicated to triathletes focusing on longer distances. Extremely tight fitted, yet comfortable to wear due to superb elastic fabrics that were developed and perfected at the NTNU in collaboration with world-class athletes like Craig Alexander, Kristian Blummenfelt, Casper Stornes, Maurice Clavel and Lisa Nordén. Results showed that including a golf ball structured fabric on the shoulders and aerodynamic stripes on the thighs reduces drag and increases speed with the same power output. These fabrics are much faster than skin and therefore added we length to the arms and thighs in our updated version with a new cuff using an anti-slip silicone that holds it in place.

    • Innovative and uncompromising
    • Quick drying
    • Research based, tested by pro triathletes 
    • Extreme tight fit

    The back and the front of the suit consists of a new and very quick drying, ventilating and elastic fabric to make it better for all three disciplines. The suit has an extra-long zipper for increased ventilation and has a split at the front, making it aerodynamic while cycling and being comfortable on the run course.

    The pad is developed in cooperation with Italian-based specialist Elastic Interface, focusing on longer distances providing protection on the bike and freedom for the run. The two pockets on the back have a new solution with elastic inputs, slightly angled, one on each side, making the access to bars and gels very easy.
