      The Core Trisuit from Castelli is made from a lightweight blend of fabrics to give you the best support in the saddle and as you run. It’s all thanks to the high quality KISS Tri Seat Pad, made with a slim profile that gives padded comfort in the saddle, then disappears when you hit the water and the tarmac. It retains its great fit however, thanks to the GIRO elastic at the leg hems, which helps you focus be your best in all three stages.

      Outside of the pad, both the Tempo3 Light upper and Pace 3 shorts section carries offer that fantastic fit and aero performance. It also features a subtle pocket construction, ideal for carrying nutritional snacks to keep you fuelled at all times.

      A YKK Camlock zipper rounds things out to allow you in and out of the suit with ease, helping you set the new standard in your triathlon times and confidence.
