Dual core performance.

Updated with new fabrics and features, the Core 2 Tri Short from Castelli is your perfect foundational piece of tri apparel. Featuring a highly breathable, lightweight construction, these shorts provide the optimal amount of compression for training runs or short-distance races. Inside, the Core 2's feature a lightweight, non-intrusive liner without padding for running comfort and riding support.

Note: Castelli tops and bottoms are designed with a performance cut that often runs smaller than that of other manufacturers. Consider sizing-up one size to ensure a comfortable fit — e.g., if you normally wear a Medium, select a Large in Castelli. Feel free to contact us with any questions or concerns.
