Tri harder.

Designed to dominate all disciplines, the Castelli Free Tri Singlet for Women boasts a lion's share of tech fabrics to take you seamlessly from water to air as you charge through through transitions without need for a wardrobe change. It combines lightweight and breathable stretch fabrics together to mold to your body and minimize drag while you dive into the water, and quick-drying technology to keep you from feeling soggy as you embark on the bike leg.

The Free Tri Singlet features a half-length zipper with an oversized tab in order to ease entry and exit and to allow on-the-fly heat dumps. Castelli also incorporated two rear Free Aero 2 pockets which are large enough to carry your race-day nutrition but feature side-oriented openings to maintain a low profile for aero- and hydro-dynamic benefits. The singlet is finished with Castelli's Snap Hooks, which attach it to compatible shorts for a seamless, triathlon fit.
