Castelli Core Tri Singlet - Women's



Show Description

Depending on your preferred race kit, wear this as a high-performance top or hook it onto any Castelli® tri shorts to create a full suit. Stretchy fabric dries fast and fits close, so you can slice through the water and sail through the wind. The pockets are specifically designed to hold what you need to keep fueled without compromising your aerodynamics.

  • Made of a quick-drying fabric blend that keeps the drag low and breathability high.
  • YKK® locking half-zipper for self-venting and temperature regulating.
  • High-capacity pockets can hold a lot of energy gels, while still maintaining an aero silhouette.
  • Sublimated graphics.
  • Lined front for peace of mind in the water.
  • Create a full suit by attaching to any pair of Castelli tri shorts. Hook attachment system does away sagging shorts or exposed skin during your race.
