Almost everyone wants to race in a short-sleeve race kit these days. While suits in triathlon are the norm, there are still arguments for a two-piece race uniform, especially when you want to change outfits for the three disciplines or minimize your pit-stop time in a race. This jersey combines all the benefits of a short-sleeve suit with the versatility of a top and your favorite triathlon short. The revolutionary sleeve and shoulder construction demonstrates Castelli’s DNA of performance and aero optimization backed by numerous CFD simulations and wind tunnel tests. While aerodynamics is key, you don’t want to compromise comfort. Patterning that is tailored for all three disciplines and soft fabrics with good breathability and UV protection support your unique race-day experience. Details like two generous rear pockets for nutrition and our SnapLock system to clip the top to your Castelli triathlon short ensure that you don’t have to make sacrifices when picking a two-piece kit over a suit.
