With its two large back pockets, unusual in tri gear and invisible to wind and water, the Castelli Women's Free Donna Tri top is ideal for long days and long-distance rides.
Castelli constructed the Free Donna Tri Top from stretch polyester with a hydrophobic treatment. So, it glides through the water with hydrodynamic properties akin to the newest swim skins. It also happens to dry very quickly when you get out, improving comfort post-T1. Additionally, Velocity mesh at the back improves aerodynamics and provides cooling airflow.
The Tri Top features a full-length zipper with an oversized tab in order to both ease entry and exit and to allow on-the-fly heat dumps. Castelli also incorporated two rear pockets that are large enough to carry your race-day nutrition. Additionally, Castelli covered them with what it calls 'fairing flaps' in order to maintain a low hydrodynamic profile in the water.
The Castelli Free Donna Sleeveless Tri Top is available in six sizes from Small to 3X-Large and in the color White/black/pink.
