2023 TRIMARNI KIT STORE IS OPEN - ORDER NOW



The Trimarni kit store is now open!!

If you love to use and move your body, cross finish lines or use your body to live an active lifestyle, we believe that you are the ideal human to sport a Trimarni kit. 

When you sport Trimarni, you are representing our brand. We want you to be proud sporting your Trimarni kit as you inspire other athletes and fitness enthusiasts to work hard for athletic excellence but not at the cost of compromising mental and physical health. Your support means the world to us and we love seeing humans doing incredible things with their bodies. 

Engineered for top-level racing, Castelli is dedicated to making the fastest clothing in the world for triathletes and cyclists by using the most advanced fabric technologies available. We are confident that you will love the reasonably priced, comfortable and functional kit items.

And because we can't have you sporting an old design on a new kit, we are excited to show off our new design. 


The darker kit can be purchased in male and female sizing and brighter kit is available in women sizing.
