Castelli have made this jersey for the rigours of indoor training. The 3D Mesh fabric allows maximum airflow for cooling while the 100% polyester content means it provides maximum moisture wicking.

Made on the limit of not being too transparent in case you want to wear it for group training sessions, or if you're using it at home and want to take it off after warming up - and the long zipper means it comes off easily.

There's a couple of pockets on the back so you can stash your AirPods or phone or headband, or whatever you haul to your training station. They've kept the collar low and the waist short for maximum cooling. It also just happens to be a great hot weather jersey that you can pull back out in the summer.

  • 3D Mesh lightweight 100% polyester wicks moisture and dries quickly
  • Semi open mesh allows maximum air flow without becoming too transparent
  • Full length zip makes for easy on and off
  • 2 rear pockets for stashing whatever you need
  • Can be used as hot weather outdoor jersey
  • Weight: 88 g

Colour: Light Black
