Castelli Women's Insider Sleeveless Jersey Description:

The Castelli Women's Insider Sleeveless Jersey is ideal for indoor training rides or spin cycle classes. Castelli made this jersey for the rigors of indoor training, incorporating 3D Mesh fabric that allows maximum airflow for cooling while the 100% polyester content means it provides maximum moisture wicking. Castelli made it on the limit of not being too transparent in case you want to wear it for group training sessions, or gym visits. It has a zip pocket on the back so you can stash your AirPods, phone, headband, or whatever you need close for your training station.


  • 3D Mesh lightweight 100% polyester wicks moisture and dries quickly
  • Semi open mesh allows maximum air flow without becoming too transparent
  • Rear vent window promotes further ventilation
  • Zip rear pocket for stashing small essentials
  • Can be used as hot weather outdoor jersey

Castelli Sizing: Many Castelli products are designed with a European race-fit. It is not uncommon to size up one or two sizes for the right fit.

Note: All measurements are provided by the manufacturer and may vary depending on how measurements are acquired. Castelli instructs that for best results measurements be taken over underwear. Castelli recommends sizing up if measurements fall between sizes for a better fit.
