The Castelli Women's Free Tri Top is a piece of apparel specifically designed for female triathletes. It's engineered to provide comfort, aerodynamics, and functionality during all phases of a triathlon, including swimming, cycling, and running. As of my last knowledge update in September 2021, here is a general description of the Castelli Women's Free Tri Top:

Description:

Material: The tri top is typically made from technical fabrics that are quick-drying and water-repellent, ensuring that it doesn't absorb excess moisture during the swim and dries quickly to avoid chafing during the bike and run.

Aerodynamic Design: Castelli pays attention to aerodynamics in their triathlon gear, including the Women's Free Tri Top. It is designed to reduce drag and enhance your performance during the cycling portion of the race.

Form-Fitting: The top often features a snug and form-fitting design to reduce wind resistance and stay in place during your activities. It's meant to provide comfort while swimming, cycling, and running.

Short Front Zipper: Many tri tops, including this one, come with a short front zipper for added ventilation and ease of getting in and out of it.

Two Rear Pockets: Triathlon tops usually have pockets in the rear to store nutrition gels, energy bars, or other small essentials during the race.

Chlorine-Resistant Fabric: The material used in the top is typically chlorine-resistant, which is essential for triathletes who train and race in pools.

Sublimated Graphics: Castelli often uses sublimation printing to create vibrant and long-lasting graphics and colors on their tops.

UV Protection: Many triathlon tops are designed to offer UV protection, helping to shield your skin from the sun during outdoor races.

Reflective Details: Safety is a key concern, so the top may include reflective elements to enhance visibility during low-light conditions.

The Castelli Women's Free Tri Top is tailored to meet the specific demands of female triathletes, providing a balance of comfort, aerodynamics, and functionality to help you perform at your best during each stage of a triathlon. Since product details can change over time, I recommend checking Castelli's official website or consulting with a reputable retailer for the most up-to-date information on this product, including its availability and specific features.
