Designing shorts for triathlons can be a daunting task if you don’t know what you're doing. Luckily, Castelli has loads of experience here and when designing the Men's Free Tri Short, it carefully considered all three disciplines. It's crafted to help you excel in the discipline you're currently in, while not presenting any detriments while transitioning into the next leg.

The Free Tri Shorts are constructed with Castelli's hydrophobic Instadry Speed fabric. This material helps you glide through the water with minimal absorption that can add weight and the possibility of a rash later on. The next-to-skin anatomic fit offers great support for hard-working muscles and is streamlined, for better aerodynamics, encouraging a fast bike split.
