Tri to the core.

The Castelli Men's Core Tri Top is packed with features designed to get you the win. Featuring the same innovation that Castelli is known for but without the high price, the Core line is perfect for the aspiring triathlete.

Starting with the aerodynamic Tempo 3 material, this lightweight, breathable fabric provides a high amount of stretch. It also offers plenty of moisture wicking and dries fast as you transition from your swim to the bike leg. This top also features Castelli's Speed Hooks, which create a connection point between the jersey and compatible shorts. The Hooks do double duty, keeping your jersey from riding up while simultaneously improving the aerodynamics. Speaking of aerodynamics, the jersey also provides two high-capacity aerodynamic Free pockets.


  • Tempo3 Light stretch fabric.
  • Two high-capacity Free Aerodynamic pockets.
  • Speed Hooks integrate with compatible shorts.
  • Claimed weight: 89g.
