Castelli - Core Tri Suit - Men's - Black - 2025

Castelli - Core Tri Suit - Men's - Black

Top short-sleeve suit for your first triathlon experience or budget-minded athletes.

A suit that has everything you need on race day, in a more economical package.
Just like for our top models, we also use a short-sleeve construction, because newcomers or budget-conscious athletes do not want to miss out on aerodynamic advantages and a professional look. We have directly adopted the construction of the two back pockets and the KISS Tri seat pad from our top-of-the line models.
With excellent stretch and a forgiving fit, the Core suit is your go-to solution for training and racing at all distances.
